And? You can install the 64 bit version on a Macbook Air. It just eats up more of your partition. You probably had a bad burn. Helps to slow down the burn speed when burning an ISO to disc.
You should really run it in 64-bit. Just reburn and reinstall! I personally don't want to "waste" my MBA drive space with Windows. But, I may do it when I get my next MBA with 256 GB SSD and 4 GB RAM, dreaming... of the future.
Should I not even consider on my Rev. A based on your experiences? I really could use a nice version of windows, mainly for programming and I also enjoy being on the bleeding edge...just curious.
