>For a tool that I use every single day that was worth it for me Well, sure if it were guaranteed to prevent or cure RSI then either spending hundreds of dollars or getting out the soldering gun would clearly be worth it. But I suspect you didn't get my point, which is that I spent the $270 in 1997 dollars for a Kinesis Advantage (and later on a different mechanical board) and it did not work for me. Or more precisely it did work for a month or 2 -- not because the Kinesis was more innately ergonomic than any other board, but rather because I wasn't used to it. Once I got used to it, it stopped working.
