I think it's lame that it has no number pad, although it's smaller, I wouldn't ever take it anywhere so I don't need it to be portable! I think it would be smart for Apple to sell one with a number pad as well. I wouldn't want to get a wired one, I LOVE having wireless keyboard and mouse so I can just pick up my MBP and go without unplugging stuff. Also, the keys are so much like the MB's, and half the reason for getting an external keyboard is because it's better for you if you type alot, avoiding carpel tunnel and such... but if you have an external keyboard that's exactly like a laptop keyboard that kinda defeats the purpose, in my opinion. However, I've never typed on an MB... but laptop keyboards in general tend to be bad for you if you type a lot on them.
