Windows Vista must have wasted at least a week of my time. Vista has the most RANDOM instances of Blue Screen of Death. You can be doing anything or nothing then BAM! Restart!

Then there were all the compatibility issues, driver searching, crashed IE and FireFox sessions, and trying to get 3 seperate hard drives to work when it turns out I had to reinstall windows to get my usb ports working. Such a pain!

If I had to choose between a C64 interface where I had to type commands or Vista I would be happy to type RUN BOOT all day long. At least I know it'll never crash on me!!!
