This is not unique to the Kindle, though. All the current generation of eBook readers have these issues (with the possible exception of the iLiad, but that has a whole bunch of different ones). These are, though (IMHO) minor flaws in excellent products. Hopefully in all our machines (Kindle, Gen3, etc) they will be addressed by future software updates.
The shortage again is not unique to the Kindle. The Kindle, Sony, Gen3 - all are in short supply. It's more than likely due to limits of manufacturing capacity for the screens, since all three machines use the same screen.
