Tried various smartwatches and the problems always came down to one thing: battery.
Some of the watches batteries last a few days or a week but the screen remains dark and to see time you have to touch the screen our flip your wrist which gets on my nerves.
Now wearing a regular watch and each time I look at the time I’m in awe of the miracle of seeing the time displayed clearly.
When they come up with a watch that can keep the screen lit for at least a week without recharge I’ll reconsider…
Not for myself but a client who was running a game server. He wanted to tweak the number of ticks/second that the kernel interacted with CPU. Didn’t even know that this was a parameter and after a few attempts, according to him, never went on that server myself, made a huge difference and he claimed having grabbed a good part of the market because of that.
After that familiarized myself more with the stuff in there. But that was a good while ago, before most of you guys were born.
