As another data point, I use the mouse in a normal position (off to the right), plus I don't have an ergonomic keyboard, a special chair, or perfect posture. I've spent at least 5-6 hours a day on the computer since the 90s (and played an inordinate amount of video games), and I've yet to experience any wrist or neck pain.

An ergonomic specialist would reject everything I do, and you probably should too, regardless of how it works for me.

Yet another data point. I coded full time at work for 14 years without having any problems at all (an therefore not paying any attention to ergonomics either).

Then in 2005 I started having problems with my arms. It got so bad I thought I had to quit programming all together, but I managed to sort it out, and today I can work without problems.

The most important part of the solution for my was to start using a break program to force me to take regular breaks (preventing the problem in the first place instead of treating the symptoms). I also started to use a split keyboard without a numerical pad, and using a penclic pen-mouse.

I wrote about it at http://henrikwarne.com/2012/02/18/how-i-beat-rsi/ and it was dicussed here at HN here: http://news.ycombinator.com/item?id=3635692
