When I go to answer an IM, alot of the time I end up doing other computer activities like checking some website or my email, or vice versa. Having specialized devices would make it harder for a person to fall into such habits. I shouldn't have to resist the urge everytime I get a message to go check some website, play a video game, or just listen to some music. When I'm doing work on the computer maybe it's not so good the internet is a only a click away.
Squats or any overhead exercises can just make the back pain worse and actually cause injury. Aerobic exercise especially running is the best thing you can do for your back.
