I have a Dell Inspiron 1420 (2008, and no touch-screen) and it is currently running Windows Vista home premium. I am planning to upgrade it to some sort of new operating system, but am having troubles deciding which to use. I currently have windows 8 in a virtual machine on my desktop, but I feel that I am not getting the full performance due to it being in a virtual machine. Now I know that a lot of people dislike Windows 8, and I honestly don't know what to think about it. But at the same time many people disliked Windows Vista, which happens to be my favorite OS. So basically it boils down to if I should use Windows 7, which i know how to use (I have it on my desktop) or use Windows 8 which I don't really know to use. And just to make it clear, the only reason that I don't just put Windows 8 on there is because I don't know how well it will perform with a Core 2 Duo, and 3 GB of ram, but I do know what kind of performance I would be getting with Windows 7 because my sister has an identical laptop to mine and it has 7 on it.
