How can you buy without the OS pre-installed when you buy a cheap laptop about $400? So if you want to install Windows Ultimate yourself, and want to avoid having to pay for a Windows Home Premium pre-installed but you won't use anyway, is there a way to buy a laptop that doesn't have an operating system installed but comes with the latest core? (I'm under the impression maybe if I just buy a 3 year old cheap laptop it might not be powerful enough to run Windows 7 on it?)
