Perhaps I didn't use the correct verbage. The ergonimic keyboards aren't really designed for "comfort". They're designed to help reduce the possibility of getting carpal tunnel syndrome. However, using an ergonomic keyboard alone is not enough. Most people need to redesign their work areas too.

I find switching to a laptop keyboard easier than switching to a regular full-sized keyboard.

>I don't find the older keyboard layout unnatural at all, and I have no comfort issues with it. But forgetting about that for a moment, I'd be interested in your experience: after learning to use an ergonomic style keyboard, do you find it difficult to switch back and use an older style one, like on a laptop PC?
