I want to clean install windows 7 after formatting disk. This doesn't sound like a great idea, but I need this for couple of engineering softwares to work. I don't want to spend my nights in computer cluster or at friends pc... I have heard, I will encounter following issues: - battery will drain faster - graphics driver for x64-bit version - camera - iPhone backups and syncs (music, video, cal, contacts and apps) - I would need a external mouse for right click. I can live with all of the above problems except graphics card drivers. Can anyone provide feedback or useful links they have refered to installing Windows 7?? Thank you in advance, Ciao.
