Vista made me a switcher

I’m using three Computers. I’ve a company desktop for development purposes, a company notebook for visiting customers and developing software on the road and a computer at home. My computer at home is used for developing, managing private pictures, cutting private videos and burning them and a lot of other things. Most of the stuff Im developing is written in Java, I’m also using a linux server at home for SMB sharing.
Since about half a year the Windows XP Installation on my PC at home was broken, always I had to press the reset button after a cold boot during startup phase to let the PC come up.
Also Outlook wont save my settings (display position, items in toolbar, and so on). I decided to reinstall the Computer - and because I’ve to less time and I need the PC for being productive, I thought to wait for Windows Vista.
