Are you at any chance a student or a gamer? The reason I ask is because I am in the same boat, but as a student I will quality for the free iPod discount that will be rolling around towards June. So the BlackBook is $1400 with student discount, but after the iPod discount (I sell it on eBay) I will get it for about $1250 ($50 taken for expenses with eBay and time posting).
The reason I ask about games is that AnandTech recently mentioned the next platform in a review of the MBP (
http://anandtech.com/mac/showdoc.aspx?i=3246&p=2). Here is a excerpt from the article:
"Montevina will also use a faster integrated graphics core (helping the MacBook) and a lower power chipset. . . . The timeline for all of this is pretty simple; you can expect Montevina before the end of 2008 (Intel lists it as June on its internal roadmaps, but you can expect to see it in notebooks anytime in Q3)."
If you can wait definitely wait, especially if your a student or care about gaming.
