I upgraded to the Apple wireless keyboard with my new iMac. However.... mine has BIG problems with Bootcamp and the CAPS LOCK key. Pressing CAPS = instant dead keyboard and/or endlessly repeating keystrokes. It does revive itself eventually after a few minutes... Especially annoying when gaming as I'll accidentally press it while playing COD4 and end up running backwards for 5 minutes unable to do anything else but shoot! Horrific bug, Apple - what are you thinking?? I haven't installed any other drivers other than the ones which come with BC, so perhaps it is user error?
