I will stay away from Rev A products for a while. During which, I check on how early adoptors are being treated by a Rev A product. I won't be a guinea pig by spending close to $2 K money on a potentially buggy product (because of its new architecture). For now, I feel I am all set with the conventional notebook computers as I have already enough and the ones I have now are more than capable for my computing needs for now (and for the next year or more at least).
The only thing I may buy another computer in addition to my current stable of computers in the next year or 2 years from now is a tablet PC.
Of course, if my Mac breaks down, then, I will buy another Mac. But, since I have 4 Macs now, if one breaks, I can use the rest of 3 and I hope I can wait out till a Rev B or C (ie. more matured version of Intel Mac) comes out into the market.
