Here's why: 1) The new chips won't be available in bulk for at least 2 weeks and they need at least a week or two to install em. Or so. 2) All the people they took off the MP project to help launch the iPhone are now back and it's gonna take them a few weeks to get organized. The upshot is the new MP will be much smaller and unibody (think new Mini). 3) And the new case design has this one thingy that is sorta off that they're having to correct because Steve says so. It's not like anybody would notice it, but Steve is the man and it's a bad career move to tell him off. I was like, "Hey Steve man, don't worry about that thingy," and he was like, "I pay you to worry about the thingy. What we do is worry about thingies." I'm paraphrasing. 4) Because we need hope, damn it, and nothing gives hope like putting down a date.
