We personally adore Microsoft's Bluetooth Mobile Keyboard 6000, which is about as curved / ergonomic as Bluetooth keyboards seem to get these days. But if anyone in the crowd knows of a legitimately "split" keyboard with a BT radio in... well, give the world a shout in comments below!"I'm starting to feel the effects of years of typing on crummy keyboards, so I want to spare myself further hand and wrist pain. I like the Microsoft Natural keyboards, but I'm working with my iPad most of the time, so those aren't really an option. What (if any) is the best Bluetooth keyboard as far as ergonomics is concerned?"
