I've managed to avoid carpal tunnel syndrome due to avoiding all the recommended advice concerning good posture.. My posture is a big no-no, with my feet up on my desk or on a box of files I should have put away months ago, with my keyboard in my lap. I'll sometimes find myself with my feet up on top my crt--at home anyway. If I tried it at work I'd probably owe the employer a new lcd. I think the reason this works is that I'm always changing positions, trying to find a comfortable position in my $50 staples chair. It also helps that my fingers have transcended the home row. Nothing is ever typed the same way twice. The only problems I have had is some minor strain from using the scroll wheel instead of the arrow keys to scan through thousands of pages.
