I am starting to have a lot of pain when I am working or playing on the computer, about 75% of my job is on the computer and I am starting to get a lot of pain in my shoulders and my TOS is flaring up due to the computer work.

has anyone tried any ergonomic keyboards and had any luck?

I saw one in an add on TV where the keyboard was actually part of the chair and to either side of the man's legs. I think this might be a good keyboard for me. Has anyone tried a keyboard like this?
