Just incase anyone is interested in the Windows experience Index: I have the higher level MBA 11'' 2012 (1.6ghz, 4GB, 128GB) A few points: Windows install takes about 12GB after turning of hibernate. Bootcamp drivers took a while to download before the install, over an hour but I was on a slow connection. The core Windows install only took about 15 minutes. Bootcamp driver install took about 5 minutes. Installed using a Windows7 iso from a USB drive, really brilliant way of installing an OS. I will be testing a few games on my Windows install (Fifa 12).
