I love those crazy ergonomic keyboards...I use an old Natural Keyboard Pro at home, it's just the best keyboard I've ever found, it prevents RSI entirely and it has a little USB hub -  but they're stopped making that model and the latest ones aren't up to much...well, I just discovered this - it's the Logitech version of the same kind of keyboard,comes with a mouse - and it's wireless! Best thing though it that it only costs £19.99 (my original one cost me £80 about 3 years ago) - that's cheap even for a normal wireless keyboard, this place also has them (US), but their cheapest price is $54.99 (usual price $129.99)...so anyway,a bargain, it has great reviews on the Amazon UK site. If you haven't tried one of the ergonomic keyboards, I really recommend it!
