I Filed the Sharp Corners Off My MacBook for Comfort

I modified my new MacBook Air by filing down its sharp edges to improve wrist comfort while using it on my lap. Despite initial fears of damaging the device, I used a metal file and sandpaper to achieve a smooth finish that went unnoticed by others. This experience reinforced my belief that a laptop is a tool meant to be used, not feared.

The moment I am too scared to do something because I might damage the tool, it stops being a tool.

    Nitpick: those are (sharp) edges, not corners. Maybe the next generation of MacBooks will also actually have exactly 90° non-rounded corners? I guess that's the next logical step...

    Also, TIL that Bosch also makes files. I was under the impression that they only made powertools (or electronic measuring devices, or other things with a battery or power cord).

    Great article and happy to see that I'm not alone. I don't get why on such a well thought-out and built device as this, the corners are so sharp.

    From how I use the trackpad, the bottom of my thumb always feels sore-ish after a day's work and it took me a while to trace this to the sharp cornern of my macbook.

    Yeah the sharp edges have bothered me since they started with the unibody. Luckily I'm completely off Mac these days. But really the last mac I enjoyed using was my powerbook. It had really nice plastic gaskets for the edges, a keyboard with really good travel and cupped keys, it was wonderful.

    I got a plastic MacBook eventually which I filed down too because the edges were really sharp there. And plastic is easy to file. Also replaced the screen with a matte version, on the plastic MacBook that was also easy because the screens were readily available and there was no glass overlay.

    Then I had a unibody MBP 15" matte. Less sharp and with off factory matte display. Not great keyboard though.

    The current MBP I find abhorrent. Even after they switched from the horrible butterfly mistake the travel is still way too shallow. I just can't work with that anymore. These days I just don't buy laptops anymore. Only desk PCs.

    I love the animation on the background of your website.

    And I totally understand what you mean about using a tool, if it's too delicate to do the job, then it's not doing its job. Imagine buying a hammer and trying to keep it clear of scuffs, it's obviously going to impede your work.

    I didn't have the heart to make something like this on my M2 Air so I did a new edge to 3D-print and attach to the edge. Works really well and have lasted more than 3 years to this date.

    This is my number one complaint about the M-series MBP line. Especially true of the cutout in the middle that has points so sharp they can cut you if you accidentally scrape it with your hand.

    It's always entertaining for me to realize that there are people who find very annoying things that I don't even notice.
