My 2006 macbook is showing its age and I was all set to get a new MBP but fell in love with the weight of the air. I've been holding out on getting a MBP (since the 13 was still core 2 duo) for the new core chips...but trying out the air has me confused now. Is it unreasonable to expect a core i5/i7 and thunderbolt in the next air revision? The core 2 duo is the only thing holding me back for now and I prefer buying every other gen chip when it comes to my purchases (my core 1 duo -> core -ix).
