Hell, they sell the 15" TiBook at the Umich Campus store for $2138 (applecare included). I'm going for the 17 inch because of:
1) The big physical real estate (knowing apple, they aren't going to push the resolution of their screens for a while, 15.4" or otherwise - after all the 17" AlBook's screen is based off the 17" imac)
2) The weight isn't really much of a concern, I'm used to carrying around many many pounds of books, and my mum's Dell laptop weighs more than the 17 inch.
I've carried that sucker around all over...
3) When you actually make a mock-up of the 17" AlBook footprint, it's not nearly as big as you imagine. (Yes, I _am_ that sort of geek.)
Also, money isn't much of a concern for me cos this is coming out of my parents' money - so I guess I'm terribly biased
I just feel bad for Apple because they have boneheads in the marketing department. After all, they announced this with a load of hoo-hah, complete with FULL-PAGE ads on major magazines and newspapers like TIME and the NYT. Now it's been two months, and at this rate no one will remember anything ('specially the pontential switchers lured by the said TIME ads like me) about these Laptops when they actually come out, while Centrino sways the market backed by Intel money.
