Below are few issues I faced before I could get everything working fine. Once Windows is installed, you continue with the installation of the devices which can be a little tricky. My installation was dual-boot configuration – having both Mac OS and Windows 7. You start with Apple Boot Camp CD 1 and proceed from there. The basic installation of the OS (Windows 7) is similar to doing it for Vista using Boot Camp. Occasionally Windows doesn’t shut-down gracefully, when it happens you got to force switch-off (which in MBA means holding the power off button for few seconds till you hear a POP sound).
After fixing few issues with drivers and boot camp, I am overall happy. A few weeks back I decided to repave my Laptop ( Macbook Air) and go with Windows 7 Build 7000 (yes I know in few weeks we will have RC :-) ).
