Keyboard
The new keyboard (Digital Media Pro) arrived to replace the generic one that came with the desktop. So far, so good -- the key feel is a bit "mushier" than the old one, but in general it's more comfortable. Unfortunately, the new keyboard and driver install didn't fix the one recurring annoyance I have with the machine (it won't wake from sleep mode in response to the keyboard or mouse; I have to press the button on the case).
