my 2 cents for MBA:
1. I am not all that hot for the design of the MBA, contrary to many. Other than it being really thin, I don't find it all that pretty or good looking. I still like the design of MBP more.
2. I am not so sure about using 1.8 inch HD. Didn't Apple tell people that using iPod as a HD for computer is not really a good idea and it may damage the HD down the road?
3. If Apple is billing the computer as wireless centric notebook, I find it confusing...
