I just got back from the apple store to check out the 'books (again) and the new mighty mouse. As far as the mouse goes, my overall impression seems to be "meh" but the jury is still out. Anyway, Apple had a new advertising campaign in the front window, displaying all the ibooks and powerbooks with a slogan saying: "The only books you will need for back to school" or something to that effect. Definitely pushing the back to school thing. I am wondering if this means no powerbook updates before the school season (sept). I know a lot of people are holding out till the end of this month, but is this evidence that they won't see any action?
