I'm a newbie as regards to the mac world, but I've been using computers for more than 20 years now. So, while I may not understand the apple world, I (perhaps with arrogance) think I understand the digital world. Consider this as a disclaimer while flaiming
Answer thread-wise: wait. Now there's no point in buying before tomorrow and the special 12 event. If you didn't need the book today, you almost for sure don't need it till friday
Concerning pb prices: yes, they're overpriced. But, please, listen before sighing. They're not badly priced for their computing experience, as they run the professional software which is on-sale NOW. They sport a magnificent os and a gorgeous personal apps suite, iLife. They're well engineered and good looking, and blah blah blah.
But, they're simply overpriced in a sad capitalistic way. Demand is high, offer is in the hands of a monopoly, Apple Inc. There's no point in seeing the whole problem otherwise. Mac Os X is great. Ok, but Apple sells it for less than 200 bucks, worldwide. iLife sells for less than 100. They do not use a single piece of exotic hardware when it comes to memory, disks, screens, interfaces. We're paying A LOT for what simply boils down to almost 3 year-old design and appleish experience. Not for hardware value. Some will find it acceptable, some won't. While I agree that the whole experience is great, I do not understand sentences like "you pay for what you get", unless you specify that we also buy the guts of Apple monopoly (relative to the mac community).
PLEASE note that I would NOT love to see Mac compatibles. So I am willing to pay. If less people rushed out to buy pb, perhaps they would cost less. Perhaps not, who knows?
BTW, I am waiting for a new pb. I am what magazines call a road warrior. I do not need photoshop or video editing. I need a book with very long battery, which doesn't burn my legs, with very good wifi range, and that doesn't weigh more than 1.5 Kg. Please compare the thinkpad X41 with the pb 12' as long as we count on this requisites. Here, I would pay MUCH MORE than what I'd get for.
But, Apple doesn't sell such a book. So it's just getting a pb as it is for the whole Os X experience, wait for exotic updates in form factor, or buy a X41 and run Linux on it.
But please, do not tell me the price range for the pb 12' is right. It simply is not.
