...using a M$ ergonomic keyboard on a PC that is split in half like that is a PITA.
I've always found the ergonomic keyboards to be extremely comfortable to use. After working on an ergonomic keyboard for a while a standard flat keyboard feels very cramped. I'd be very interested to see what can be done with an ergonomic-handheld keyboard. The question in my mind is: how will the QWERTY layout translate to the angled keypad?
It's very doubtful that they would have a patent published to the USPTO website prior to the release of the actual device it would be used on. This seems to be more of an R&D patent that will never see the light of day (but it's still good to get the patents for these sort of endeavors, and RIM does this quite a bit). Honestly, snooping on the USPTO website for patents is a "fun" way to pass some time (I've found myself doing just that), but it rarely will reveal anything resembling useful information that pre-dates a device/product launch.
