i am sick of everything having a battery. i just want to plug it in!
i want a steady stream of power, not to have to worry about recharging and charge level every damn time i use the shitty thing that usually has a shitty battery
Wireless is super convenient but I hate all the micromanaging that needs to be done with batteries. Lithium batteries has made this generally better but there's still a lot of subtle ways that batteries like to change when you aren't looking. It's fine when you only have 1-3 batteries to deal with but it gets tedious quick as you end up with more and more batteries.
I am sick of everything having a wall-wart transformer, especially where the size or shape prevents other things from being plugged into the adjacent sockets.
