I am considering giving in and ordering a 1.5 15 inch PB - right now I am a PC user. However the main reason is it would be an xmas gift - if they come out with a new rev in January I would be pissed. It sounds like that is a good possibility too.
Its a tradeoff - wait and be happy, but have an empty xmas tree. Or give in and order it, switch to the mac platform and never look back - but in January watch the new PB and drool???
