I was thinking this exact thing earlier today. Apple eliminated the keyboard dock, and are actively showing the Bluetooth keyboard as an iPad 2 accessory. One would think they would update 4.3 to better take advantage of all the buttons. I wonder if anyone can try it with 4.3. If not, it is certainly something they should "button up" (pun intended)...so with the keyboard dock dead, how about Apple actually use all the f-keys on Bluetooth keyboards?
