#75 Why I switched from Apple Magic Mouse to Logitech MX Master 3

I switched to Logitech MX Master 3 from Apple Magic Mouse. Apple Magic Mouse has a beautiful hardware design. The problem is, it’s too beautiful at the expense of various things…

Problem 1: Magic Mouse is too symmetrical, while Logitech MX Master 3 has only one way to hold

Magic Mouse is beautifully created as a perfect symmetry. Because of that, there’s no way I can feel which way is the right orientation to hold without seeing it. I’ve experienced a few times where I was reaching out to my Magic Mouse without looking at it, and ended up grabbing it in a wrong orientation. When I did that, I couldn’t tell just from my grip. Because the shape was completely symmetrical when holding it the wrong way.

So I started clicking. That’s when I realized that I could not click. There weren’t any buttons to click underneath my fingers. At first I did not understand what was happening. It took me several seconds to finally realize that I grabbed my mouse in a wrong orientation.

This will never happen with Logitech MX Master 3. The form factor dictates the orientation of the mouse and how to hold it.

I can grab my MX Master 3 in a correct orientation without even looking at it. It’s impossible for me to grab it in a wrong orientation simply because it does not allow me to do so. 

Problem 2: Magic Mouse is too thin, while Logitech MX Master 3 fits extremely well to my hand

Another ergonomic problem of Apple Magic Mouse is its height. It’s just too thin, too low for my palm to comfortably sit on top of it when using it. This forces my hand to take a strained position. I have to lower my palm while grabbing and moving my mouse.

Compared to Magic Mouse, Logitech MX Master 3 is much taller when placed on a desk. The height makes my palm comfortably sit on top of it without having to strain my hand. It works really well, and fits extremely comfortable on my hand.

Problem 3: Advanced interactions are great, but Magic Mouse is not optimized for those

Apple incorporated a lot of advanced touch interactions into their trackpad and Magic mouse. These interactions include 2 finger swipe, 3 finger swipe, pinch-zoom, 2 finger tap and so on.

But the surface of Magic Mouse is not optimized for these more complex interactions as its a small area and the surface is curved.

These advanced interactions actually work much better on a trackpad. Because it has a larger flat surface for fingers to perform these complex interactions much more comfortably.

And while I really like seamless swipe scroll on a trackpad or Magic Mouse, sometimes I prefer scroll wheel to scroll.  MX Master 3’s scroll wheel works great in this case so that I don’t need to worry about accidental, unintentional horizontal slide while scrolling vertically.

Another thing is the horizontal scroll wheel. While I don’t use it often, it works very well especially for switching tabs in google Chrome.


With all these considered, my conclusion is that there are quite a few things that make Logitech MX Master 3 a better mouse overall. And the biggest reason comes from its excellent ergonomics, which allows me to use it for a relatively long time without strains on my hand. 

However, Magic Mouse has quite a few innovative, great features that MX Master 3 or no other mice have, and you don’t need to give up on those.

You can easily incorporate those via trackpad on your left hand, while you still use MX Master 3 as your primary mouse on your right hand.

As I described in my previous video, I use both trackpad and a mouse simultaneously and I love it.

One of the reasons why this setup works great for me might be because of the fact that I’m originally left-handed. As a result, I might have a better control and coordination on my left hand compared to a typical right-handed person.

Mouse + trackpad two hand interaction – how it started

When I used to work in an office, I used to have my laptop connected to a desktop PC monitor with a wired keyboard and a mouse. Back in the day, everything was wired, so a desk was quite a mess with all these devices and wires. And I hated it.

Because of this, when I started to work primarily at home, I wanted to minimize the device setups. For the past few years I loved the clean setup of my desk. Just a laptop, that’s it, and I loved it!

But as my vision got weaker, and my neck and back started to hurt due to leaning forward for long hours, I started to feel that my 15 inch MacBook retina display was too small. So I purchased a 27 inch PC monitor, a wireless keyboard and a mouse. I felt like I was in a heaven! I expected this though as I used to do it before. Nothing special.

However, what I did not expect was how I ended up using my MacBook’s trackpad on my left hand, while I hold a mouse on my right hand. Now I’ve been doing this two-hand interaction, and I love it! Why?  Let me explain.

Coincidentally I started using a trackpad on my left hand

Without any thoughts, I put my MacBook on the left side of my monitor. This setup allowed me to conveniently reach the trackpad with my left hand, so I did.

The reason why I did this naturally was because over the past several years, I got used to and became heavily dependent on trackpad-unique features such as 2 finger swipe , 3 finger swipe, flick, pinch zoom and two-finger tap.

Especially, 2 finger swipe within the current app, 3 finger swipe to switch between desktops, and pinch zoom are the ones that I have become so used to doing on my MacBook trackpad.

As I started playing around on a trackpad with my left hand, I realized that this two hand operation is really efficient and productive.

Because this way, I can have my left hand dedicated for swiping between multiple desktops, dragging the stage within an application, and pinch zoom in and out. All of these left-hand interactions are more about “navigating on a desktop”, while my right hand is fully focused on selecting, clicking, drawing objects.

Before, I used to do all these interactions with my right hand using a trackpad. This caused too much overuse of my right hand. But using my left hand for navigating on a screen while clicking and selecting on my right hand reduced my right hand’s overload. I really felt that I can work much faster this way. To me, this was an eye-opening experience.

Mouse + trackpad two hand interaction – unintentional synergy

I’m especially interested in the fact that a trackpad and a mouse are initially designed as separate alternative input devices. These are not designed to be used simultaneously. But I found out that both work together surprisingly well.

If you haven’t tried this and you have a similar set up like me, try it! You’ll be amazed!

I’m really curious if any of you have experienced this or not. If you have, I’d love to hear your thoughts!

#41 UX of emptying dyson dust bin

The author holding dyson dust bin.

Dyson is one of the most popular brands in home vacuum cleaner category. I’ve been a Dyson customer for the past decades. The model that we currently use in our household is called “dyson cinetic big ball animal +”. It’s the one without washable filters. Overall, I highly respect Dyson as a company, as a brand, who innovated the product category by introducing bag-less vacuum that didn’t lose a suction power.

According to Dyson, 

“It is so efficient it captures the dust that blocks cyclones and clog filters, so it doesn’t lose suction.”

Still I get frustrated whenever I clean up the dust bin.


Because I feel like I can never get rid of all the dust inside the cyclone!

Obviously, a large chunk of dust that fills up the bin can easily be removed when you detach the dust bin, open the lid and drop the dust collected.

The plastic bin itself is good.

It’s detachable from the cyclone, and you can actually wash it with water.

But the problem is, the cyclone part itself.

When you use a brush to scrape off dust, and tap on the cyclone to get the dust out from the inside, the dust keeps falling down and it never seems to stop.

Because the dust particles are so tiny, it seems that millions of dust particles are sitting inside the cyclone at all times which never seem to clear.

Those may not be clogging the cyclone because each dust particle is so tiny, and the cyclone may still be working fine, but the fact that all these particles never seem to go away kind of bothers me.

I wish that dyson comes up with a way to clean its own cyclone itself, potentially by reversing the direction from suction to blowing mode so that it can get out all the tiny dust particles out of its cyclone system, for example.

The idea of a machine having its own cleaning mode is nothing new.

We see those in dishwashers, ovens, juicers and so on. 

An air pump to inflate an air mattress for camping has a reverse mode to deflate the mattress too.

The same concept could potentially be applied to a vacuum cleaner.

I know that this could be a big challenge to do in a vacuum cleaner because if you activate it by accident, it will be a disaster, spreading all the tiny dust into the room.

But it’s an interesting problem to solve.

Maybe it comes with a special cleaning bin that you can attach the vacuum hose onto, and only after securely attaching the special cleaning bin, a cleaning mode can be activated to blow out dust inside the cyclone to the cleaning bin.

The cleaning bin should be a simple bin that you can wash with water.

Now this might be adding another extra hardware piece.

And I’m not an engineer, so I don’t know if this is even possible from a technical point of view.

But it might be worth it if it works well.

Or they might be already working on it. Who knows?

If they solve this problem, I will be a lot happier!

As a UX designer, especially if you primarily work on digital products, it’s an interesting exercise to think about UX problems that we experience on a physical product like this.

This may seem like a trivial thing, but when you think about the end to end user experience of a vacuum cleaner, cleaning the bin, cleaning the vacuum itself is part of that larger end to end user experience.

In a way, its kind of ironical if a vacuum cleaner which is meant to clean things cannot clean itself.

#31 Macbook damaged keyboard – what happened later (2020)

Simplified illustration of Macbook Pro keyboard with damaged key silkscreening

In one of my previous articles, I talked about my disappointment with my MacBook Pro damaged keyboard. I have a follow-up story on this.

Damaged keys on my Macbook Pro.

Previously I was assuming that I would probably have to pay if I were to replace damaged keys because the initial 1 year warranty period has passed.

This was not only based only my assumption but actually one of Apple store person that I talked to before confirmed at  the time.

The other day, I had a chance to go to Apple store for a Genius Bar appointment for some other reasons. I casually asked about my MacBook keyboard problem.

To my surprise, the Apple store staff said that they can replace damaged keys up to 5 keys!

So I made another Genius Bar appointment few days later.

When I showed my MacBook Pro to a Genius Bar staff and mentioned that I was previously told by another staff that they could replace damaged keys up to 5 keys without charging.

he said “OK, let me replace all the damaged keys.” after examining my MacBook.

20 minutes later, he came back with my MacBook, with the keyboard looking good! He said, “OK, so I replaced all the 14 keys that were damaged.”

Wow, what a surprise!

And I asked, “So this is all free of charge?”

He said, “yes”

Me: so as I mentioned, this never happened to my older 17 inch MacBook. Why is this happening to this newer MacBook?

Here are what he mentioned:

15″ MacBook has thinner keys compared to 17″ MacBook.

So this newer MacBook has a lot thinner keys compared to older ones.

Layered structure of MacBook keys

Each key is fully transparent when not painted so that the backlit LED shines through. 

Then you put a white layer on it. 

Finally on top of that, you put another layer with silkscreening of black with letter shape cutout so that the letter shows up in white.

Because of this 3 layer structure,  when the keyboard is heavily used, it wears off the top black layer, exposing the 2nd layer which is white.

His assumption is that because now that the entire key is thinner, each 3 layer might be also thinner, which might be the reason why this is happening more often compared to the older MacBook which had thicker keys, probably with thicker layers too.

He said that he has a 10 years of experience at Apple Store.

His explanation made sense, and I was very satisfied with how he replaced all the damaged keys of my MacBook.

I didn’t expect this to happen, so this was a pleasant surprise.

Which is why I wanted to make another video to give a clear statement and a shoutout to how Apple Store treated me with good care.

Now the question still remains.

I know that my 15 inch MacBook is definitely a lot  thinner and slicker compared to my older 17 inch MacBook.

It’s definitely a lot lighter,  so its easy to carry around so that I can take it with me to anywhere. It’s great.

But if this slickness, thinness and portability is realized at the expense of “easier to wear off keyboards” that is constantly at the risk of getting messy, I wonder if that’s worth or not.

Maybe my typing or way of handling the keyboard applied more pressure than needed which might have caused the keyboard to wear off faster.

I don’t know.

But I’m curious if Apple collected this kind of information from customers.

This type of issues require longer time period to fully observe and evaluate.

Maybe we already live in such a high-paced consumerism that companies and customers don’t care much about using one particular tech product for a long period of time because a newer product always comes out with faster performance, cheaper price, and better features so you just upgrade anyway?

It reminds me of things like mobile phone battery that dies immediately after the warranty expires, or a major car components start to break after  the 3 year warranty.

It also reminded me of Apple a few years ago that admitted that certain iPhone models had their batteries performance went down significantly after a certain period of time.

They ended up launching a special program to replace such iPhones’ batteries for free.

In a way, we are all trapped in this industry cycle, that we have to upgrade our devices to the latest ones in order to be on top of the technology trend, or in order to keep up with the highest productivity level to stay competitive as professionals?

One thousand dollar mobile phone must have sounded ridiculous in late 90s. But somehow it became a norm.

I still use iPhone 8 in the year 2020, and yes, it works perfectly fine! Because I’m a UX designer, so I feel like I always have to upgrade my phone to the latest.

But at the same time, I question this whole “have to upgrade” mentality and trend that we all have somehow blindly adopted without having a deeper thinking whether we really need it or not.
