I have had macbook air for a few days. I am using bootcamp to install windows 7 at there. The bad information is I have had to test it, which failed lot of work. We experienced the new operating system against Windows Vista SP2 and Windows XP SP3. Overall, Windows 7 offer a much more enjoyable experience than Windows Vista. Everything works more easily. The new OS takes less time to launch applications, and it's nice just to browse around its function and features. It's also very good-looking. However, it is slower than Windows XP, apart from for the boot and shutdown times, where XP has forever been a drag. Can you have any idea, how the performance on bootcamp +windows 7?
