I've been using my new base 2013 MacBook Air in Windows 8 over the past few days and I'm really enjoying it. Some observations: 1. Overall performance seems faster (!) than in Mountain lion: I can have more than 50 Chrome tabs open, Spotify streaming music and Acrobat open and have no lag or problems at all. Perhaps this is because of the implementation of Chrome in Windows, but I really like it. I have a suspicion that memory management in Windows 8 might be better than in Mountain Lion, because I have dozens of tabs open in Chrome, Spotify and Acrobat running, as well as many Metro apps open and still have task manager only showing 2.0GB of RAM used. 2. Windows 8 boots up very fast -- I'm getting to the desktop in less than 10 seconds. That's amazing. 3. I just love the graphics in Windows 8: I like how it shows you a graph with the copy rate it shows when copying stuff, I love the new task manager, and I just love the overall snappiness of it. 4. WiFi is faaaaast. I can stream HD movies from my DRLINK AC1200 router while downloading apps in Chrome and having many tabs open in it without any hiccups at all. 5. I'm getting 11 hours of battery life. In Windows. (Jaw drops.) 5. I like the Metro News app. I also generally just like reading articles, browsing the web, watching Netflix and using Twitter in the Metro mode of Windows 8. Have others using Windows 8 on the new Airs had a similar experience?
