well, i don't know where to start...
windows -> evil
linux -> good, that is pretty much doing the job
but, linux is more complicated, actually i think it is as complicated a windows, but we all frew up on windows, so it is easier for us, anyways, linux has some great stuff, but there are some essentials missing to completly get rid of windows, Flash 8 is one of them. and again, windows is missing some stuff, so i think dual boot, 2 pc, would be great
