I can't stand the wait either!!! I've been patient for quite some time now and I'm glad I didn't buy the AlBook back in the early part of October with all the flaws that have been exposed in recent months by the current owners.
As far as Macworld is concerned, I too am waiting to hear on what Steve Jobs says during his keynote. I doubt anything big will come from it in regards to a new Powerbook (i.e. G5.), but rumors circumventing the web/forums are stating application upgrades to the current iLife series and possibly the unveiling of the new mini-iPods.
The cycle of annoucing a new PB is usually quite awhile, and since the G5 Power Macs came out at the end of this past summer, and with all the issues regarding heat, I don't see a G5 powerbook in the making for atleast another year. Besides, I wouldn't want to get the first generation of anything new. I find it better to just wait and see what happens with users who buy their products right away.
I'm a college student myself, and will take advantage of the Apple Education discount on my future purchase (hopefully). In regards to your question, I checked on Apple's website and haven't really found anything concrete as stating whether or not they take legal actions (you may think it's extreme, ask Microsoft and they'll tell you talk to their lawyers about it, some companies are serious about these Education discounts) in case Apple really wants to waste their time with educational audits, but you never know, and don't take my word for it! If I were you, I'd go down to your local Apple Store (if one is nearby) and just ask what the terms and conditions are for purchasing under the educational discount. It won't kill you and as the old adage says: It's better to be safe than sorry!
One more thing about the educational discount, you say putting it in your name causes some concern, at least that's how I'm reading your post. Think of it this way: how do some college students buy a computer, software from companies that offer educational discounts when they don't have any form of payment? You can take out a loan, but chances are their parents or significant other (whomever that maybe), will buy the item for them under their name and not the students, even though it's the student who is registered at the school and is using the equipment on a full time basis. That's considered a loophole, but I would advise you take the time and see what an Apple associate says about this topic.
As far your second question is concerned, I could not tell you off hand. Some reports from users who just purchased their machines have said the delievery time took less than a week, to at most a month! I think the latter may have been due to the issues regarding the whitespots on the screen, but that's just speculation.
Good luck!
