I love ergonomic keyboard and chairs. Do you? They both help to minimize muscle strain and other problems.
I enjoy my ergonomic chair, but I've never been able to get used to ergonomic keyboards. I still can't stand to sit very long. 
Yes, I understand about the chair. I have one also because of my back. The keyboards are constructed in a v shape to allow a more natural angle.
I could probably use one of those once I got past the learning curve. I work as a freelance transcriptionist; do you think it would be useful for me to try one?
Yes, Ithink it would be extremely useful for you. Especially if your constantly typing.
I prefer to stand up and stretch or move often when I am working at my desk; I find that it helps with muscle strain. 
That's a smart thing to do. There's also an adjustable keyboard you can try.
I will think about looking into ergonomic keyboards in the future. 
The adjustable split keyboard has it split into several pieces so the angle can be easily changed.
