An end user if they are restricted from admin usage really shouldn't care what OS they are using as long as they can use the programs they are required to use. My mother the technophobe uses Linux at home. She can send her e-mails, write her whatever it is she writes, download images from her camera. She's even found her Solitaire games. The only thing she can't seem to do is click the little X button to close programs down

She knows KDE looks different to the WinXP at work, but she doesn't care.
