Yoiu got a Z1
Nitrous,
You got a Z1 because the new 15" PB isn't out yet?
I've got the "old dog" 15" and consider it a hell of a laptop - better than Sony has.
THe PB is one tough SOB - LAX security dropped it off the x-ray belt and it bounced several times on a very hard floor. I had to reseat the keyboard connection (a simple task even for an old fart like me) and it worked fine. Did replace the bottom cover later as it was really bashed. Look at the Sony and see if you think it is as tough.
Look at PC Mags recent customer service ratings for Apple (an "A+") and Sony has a "significantly below average" rating for satisfaction with tech support. I now LOVE AppleCare - they actually give a damn about helping you.
For the same amount of money you could have picked up an "old dog" with the memory maxed out and Apple Care, plus the new student version of Office. Maybe even an iPod thrown in for a bit of fun. Or a 12" PM or iBook with a 20" display for your desk.
If the newer PB's aren't available (thanks to Moto dragging their @ss) then you have 3 PBs to choose from (as well as an iBook) that are fantastic when compared to a wintel offering. I've been in both world and, when it comes to buying a wintel box, I'm outta there.
There will probably be new PB's very soon (thanks to IBM) and a lot of prople will stand in line to get one. After a month or two, however, they will be reading rumours of the "soon to be released" G5 PB and will start getting excited yet again. I've been through the laptop envy bit since the 80's and know the feeling!
My advice - look at the options available today at the Apple Store. Look at a smaller PB or iBook with the larger screen. Think about the iBook now then going for a G5 next summer, or a maxed out 12" PB to last for a few years.
There is always going to be a new Mac "coming soon" and, even if you were lucky enough to get one of the soon-to-be-released versions (which will be very difficult on your schedule) you will start reading about the G5 PB before your first mid-term exams.
Get a Mac and start enjoying it. You will still have the excitement of Panther soon, but will have the Mac experience today.
Good luck and have a great time in school!
PS. Where you're going - take a digital camera with you!
