Newbie disappointment
But for the Linux newbie moving from Windows, they will miss catching up with their favourite TV programs via ITV, Five, Sky and the like. yes, there are ways around it, but not ones to be tackled by a newbie. They will also miss their beloved iTunes.
I know too many people who have been caught out with a EEE or an Aspire thinking Linux will give them the same out of the box functionality as XP or Vista
