Lucas123 writes "While on stage at a Gartner's ITxpo conference today, Ballmer got an ear-full from the mother of a 13-year-old girl who said after installing Vista on her daughter's computer she decided only two days later to switch back to XP because Vista was so difficult. Ballmer defended Vista saying: 'Your daughter saw a lot of value'; to which the mother replied: 'She's 13.' Ballmer said that Vista is bigger than XP, and 'for some people that's an issue, and it's not going to get smaller in any significant way in SP1. But machines are constantly getting bigger, and [it's] probably important to remember that as well.' Says the mother: 'Good, I'll let you come in and install it for me.'"
