Depends on your keyboard, mouse and overall desk setup. Myself and a coworker use Ergodox keyboards to combat arthritis and carpal tunnel, but if you're using a standard keyboard and terrible posture it might be worse.
That's interesting. My setup is pretty standard, but with the millions I'll do with the book (ahah) I think I'll try an ergonomic keyboard. I put Ergodox in the "stuff I need to check". If you have any other recommendation, please don't hesitate to share :)
Before you get an ergodox, make sure your desk height, chair position, monitor height, etc. are as good as you can make them. I've resorted to using stacks of books when necessary :)
