Let me just drop in to recommend the Kinesis Advantage 2, a keyboard I bought about 6 years ago after first noticing wrist pain. It's probably my only purchase that beats Factorio in "benefit-per-dollar". I absolutely love it. Haven't used the 360 (it wasn't available when I bought it), but that looks even better.
Similar praise to the unfortunately named Ultimate Hacking Keyboard.
Split keyboard that can be rotated and titled exactly to fit your needs was the difference between bilateral pinky side pain radiating to my elbows to absolutely no pain in a matter of a few weeks.
That, and it's a damn fine, steel cased macro-able keyboard.
