ok??anyways, with 800k a year, why wouldnt they just buy a new computer just to stay up to date?
See the part above about people on Macforums not reflecting how normal people use computers. Most people don't care how old their computers are as long as they do the things they ask them to do in a reasonable amount of time. The only people who worry about staying up to date are people who post on online forums dedicated to tracking releases of new computers. No one else cares.
