Has anyone switched from a regular to an ergonomic/anti-RSI keyboard? And if so is there a type you'd recommend. I have read that it's all down to your sitting position - that your hands rest level instead of up - but I am interested to hear macrumours community members' thoughts. And on the same sort of subject, although it might need another thread, does anyone have any opinions/info re. the set up that best protects your eyes from staring at a screen too much - i.e. is it just a question of keeping the brightness down or is there some other strategy? I spend a lot of time working on my computer and will do for years to come - so I am concerned about avoiding RSI/vision problems/back problems etc. Thoughts?
