I have used Windows 8 since it came out and before due to having it at work before release. I found a very good OS, I love the retro look, I can have taskbars on all screens instead of just one like Windows 7, I can move the task bars anywhere and still have 'Start' in the bottom left corner.
Things a very easy to find, and you can still access everything, I feared that Windows would start disallowing access to computer changing programs, like the Registry.
Overall I love it!

I have a wonder as well, I have bought Windows 8, so I have the CD, is there a way of just buying the licence key, and using the disk I already have, saves having two disk.
