I would run to the Apple Store to buy one of the new Apple keyboards that were unveiled today. Judging by the photos, both wired and wireless models are essentially MacBook keyboards in a sleek aluminum wrapper.
Update: In Macworld, Rob Griffiths notes that he’s confused about the binary choice available between a full keyboard = wired and small = bluetooth. I have to agree – in fact, I think Apple might have gotten it exactly backwards (assuming, that is, that someone forced them to make the choice, which of course is nonsense). What’s the number one scenario in which someone would want to buy a keyboard by itself? I bet it’s someone who has a laptop that they use from a specific location regularly. That person already HAS the compact version – it’s built into their Macbook. What he or she WANTS is a full keyboard – but doesn’t want to fiddle with wires sticking out the side just to use it.
