Beware of these sellers offering both Linux XP and ubuntu ..... They say the XP is open software and its so great. Well it is a wonderful software, but it is not open. IT IS NOT OPEN. YOU WILL NEED A REGISTRATION NUMBER. These sellers will not give you a number nor will they refund your money claiming that the ubuntu works just fine. Yeah well go to ubuntu's website and download it. Guess how much it costs...... a wopping $0.
