Like I said. I'm holding my breath for Rev. D. If they are upgraded to a 226GB SSD and 4 GB of RAM, and hopefully (but not a real need) a faster processor, I'll go for the MBA. If not, a 13" MBP is in my future.
Don't forget some other importants points that must be addressed in rev D:
- the glass trackpad, which is present in the MBP line since a year ago
- those "defects" that plagued the MBA existence, such as the hinge problem, the screen lines, the tendency to overheat, and I'm sure I forget some
- the somewhat shorter battery life (although I understand that this is a complicate point, due to the size of large-capacity batteries)
I think those points are as important as the 4 Gb RAM. Personally I don't care of a larger SSD drive.
Oh, and maybe a couple of hundred buck less wouldn't hurt...
