It's pretty common if you have IT and finance teams that are paying attention. Sure a lot of shops let them waste away on a shelf, but that's what it is, waste. If you have fungible inventory that isn't likely to get used soon it is just a mistake it let it sit around unutilized. If it is cash, it is easier to utilize on other projects.

My previous company was overly cost sensitive, but large enough to not notice the waste. IT and procurement managed relationships with the vendor (Lenovo IIRC), and we had the workstations for 3 years officially but most people were 5-6 years. The hardware 100% just went back into storage when we cycled and would be given out to new hires when they joined. We were using Threadrippers with 128GB RAM and NVMe SSDs anyway...

Oh is that why it happens? Was wondering why the spot directly under my wrist was pitted into a sawblade. I also filed it, though just enough to remove the pitting, nothing like the OP did. It's easy for me to feel the mains frequency while gently rubbing the top surface of the MacBook while it's plugged in. Really feels unsafe, but neither me nor the computer have suffered any serious injuries yet.

Really feels unsafe, but neither me nor the computer have suffered any serious injuries yet. That's due to interference suppression capacitor in the PSU. The safety standard puts the "touch current" limit at something like 300uA (0.3mA), which is definitely in "painful but not dangerous" territory. You do need to exercise caution when plugging in other devices that are also connected to the mains, since that amount o…

> since that amount of current and voltage can certainly damage sensitive electronics

Like for instance the magic mouse. I've completely destroyed three magic mice by sometimes accidentally touching the mouse to the laptop. It'd not do much of anything initially, but at some point touching them together would kill the connection for a couple seconds, and over time it evolved into the mouse just refusing to connect altogether.

I'm glad my boss pays for this hardware because I'd be incensed to have a mouse THAT expensive break that quickly.

Like a person playing the piano. If your arms are resting, then your fingers and wrists are doing the maximum amount of reaching as you type. If you use a wrist rest you are encouraging your fingers/wrist to reach up (bend in your wrist) instead of neutral or reaching down (more natural position).

Like the people who generally get rsi from playing their instrument?

If you get RSI playing the piano then you had a shit piano teacher.

Straight wrists is good, but hovering like a pianist is not good for extended computer use.

> but hovering like a pianist is not good for extended computer use.

Why ?

If you were taught piano by any teacher worth their fee, then your position is natural, effortless and your wrists are limp without tension.

Exactly the same position as an ideal computer keyboard position.

Piano position is the best keyboard position. Your fingers are doing the work.

> save our wrists If your wrist is in contact with the edge of the laptop while you are actively typing, then your typing style has a good chance of giving you RSI. You'd be better off trying to fix that than trying to make the fast path to RSI more convenient.

Design as a practice should study interaction with the object and fix harmful patterns. Keyboards aren't new, this should be a solved problem.

> Keyboards aren't new, this should be a solved problem

It is a solved problem.

The solution is PBCAK (Problem Between Chair And Keyboard).

When people learn the piano, they learn correct position. And a good piano teacher will not allow the student to get away with bad habits.

But if people come to the computer keyboard without the piano, they have no teacher watching them like a hawk.

They then develop bad habits and those bad habits are allowed stay with them the rest of their life.

Then those people bitch and moan about RSI becuase they are typing with the most ludicrous wrist positions.

When I got into photography, I used to baby my camera equipment a lot. After all, I spent a lot of money I wanted to take care of it. Later on the topic came up online and someone noted something to the effective of: “If I saw a group of photographers taking pictures, I bet I could pick out the best photographer just based on how beat up their equipment is.” I realized based on my own experience, that was probably tr…

There's a curve. Beginners with pristine gears are babying it, but veterans just don't bump their camera everywhere nor drop them, they have the bags that fit what they do, use straps (or not) that fit them and there's little to hurt their camera. Event photographers are another kind, camera throwing is part of the job. I wonder if you feel the same about cars, expecting expert chauffeurs to have bumps all over their…

> but veterans just don't bump their camera everywhere nor drop them, they have the bags that fit what they do

Most veterans I know would not be seen dead with one of those bags that shout LOOK AT ME I AM A CAMERA BAG ....

The theft risk is just too great these days.

Most of the time they will take a standard bag, with their other stuff in it (e.g. change of clothes etc.) and just dump their camera and a couple of lenses in there. Either padded by their spare clothes or with a velcro-neoprene camera wrap cloth.

That solution also enables them to move fast instead of having to make sure everything goes into the right stupid slot in a camera bag.

So for example if it starts raining heavily (or if they have to get through airport security) it can be done quickly and efficiently.

I had a blackberry passport and it had a lot going for it(best keyboard ever on a phone) but one thing I really liked for reasons I don't understand is it had a square screen and took square photos.

Square sensors ought to be more common because they maximize the field of view for a given lens. Well, apart from circular sensors.

Human eyes have a viewport that's like a mailslot, though. A lot of screens are a compromise between area and a movie screen like wide immersive image.

CRTs might have actually liked being nearly hemispherical because glass and deflection-from-center.

Am I the only one that uses a thunderbolt dock and a keyboard + mouse + monitor setup? The Macbook itself is always closed in clamshell mode.

The only time I ever use a Macbook as a proper laptop is during meetings, and even then it is brief - looking up materials or taking notes - not nearly enough time to encounter long-term strain in the wrists.

If you are working on a computer for 6+ hours a day professionally, you owe it to yourself to get a proper workstation setup. Hunching over a laptop for hours a day is terrible for your posture and health.
