So I'm considering switching from Win 7 64 bit to the new RC Ubuntu and I have a few questions as my whole life, I have never tried Linux or Mac, just Windows. 1. What is the difference between all different Ubuntu's (such as Ubuntu and Kubuntu)? 2. Will Ubuntu support all my hardware? 3. Can I play games the same way I can on Windows (e.g. GTA 4, CSS etc)? 4. Does Ubuntu support big commercial programs such as Adobe Photoshop, Windows Office, Steam, Google Chrome, Foobar etc? 5. How would I prevent all my files deleting during the installation? (As far as I'm aware you just stick them on your HDD and they should be saved but is this true for Ubuntu too?) Anyway, if I don't like Ubuntu I can just switch back to Win 7 as I have the CD but I'm just very curious to how it is.
