Ask Engadget: best ergonomic keyboard for a Mac?

We know you've got questions, and if you're brave enough to ask the world for answers, here's the outlet to do so. This week's Ask Engadget question is coming to us from Andrew, who isn't interested in ever getting CTS. If you're looking to send in an inquiry of your own, drop us a line at ask [at] engadget [dawt] com.

"I bought my first computer from Apple a few months ago (15-inch MacBook Pro) and I've been using it extensively around campus. I didn't give it too much notice at first, but the keyboard is making me develop wrist problems (possibly carpel tunnel?). My wrist has been hurting so much that I couldn't sleep because my wrist would keep twitching. I bought a Logitech Wave Pro, which helped my wrist problem a lot. Problem is, Logitech dropped OS X support for the Logitech Wave almost two years ago, and many of my buttons are mapped incorrectly.

Which ergonomic keyboard would you suggest? I'm open to anything. Bluetooth is a bonus so I don't have to worry about a receiver, but if that degrades the performance / speed of the keyboard then I don't want it. Thanks!"

We know Andrew's not alone here. There simply aren't enough legitimate ergonomic keyboard options that work perfectly with OS X, but hopefully there are one or two that have really made you folks happy. Let us know in comments below, cool?
