So I'm building my mother a computer I named "the facebook cruzer" because all she does it facebook. Anyway I oped for OEM Windows 7, rather then paying out the a** for retail. So my question is, is it difficult to install an OEM version of windows 7 or is it the same. As in pop in the disk install done? Just curious, I already know that the OEM is tied to the motherboard and no MS support so i'm just wondering if its any more difficult. If it is I might just install Ubuntu.
