Yea and hopefully this time around they bring back a FW 800 (although it's on it's way out the door) and a DVD x8 drive. I hope they use that new Lithium-Ion Battery technology too. Including the option to add a more powerful video card (such as the mobility X1900 when it's released) would be nice too, but then it may get too thick.
Definitely wait for the second revision
Then trade your old one in if you still want it bad, but really the new Intel macs won't be totally worth it until next year around this time when more software has been converted and it's totally Apple's standard.
