On the topic of mac keyboards and mice, I've never had any uncomfortableness or pain at work, until I started a job where I was given your standard Apple combo of peripherals.

Suddenly, pain everywhere. The tips of my fingers were burning after every keystroke, some of the muscles/tendons in my right wrist felt like they were about to snap after using the mouse for a few hours.

How are these products still on the market? Two weeks in I bought my own mouse and keyboard and haven't had a single bit of pain since.
