The Truth:
The current powerbook 12in is an awesome machine...its a rev E and reliable, it runs software natively, and within reason, is really fast. When I compare my powerbook to other's windows laptops it runs rings around them. However, since my girlfriend got a mbp, it seems slow by comparison, which really does hark to what we will see relatively soon. The issue is though that if your using ilife, surfing, office work, then the current model will be wonderful, it is only if you really need lots of power that the mbp becomes essential.
