the only $2500 computers we sell at my best buy are sonys.....sonys are really expensive because, well their sony. They come with a decent software package too. The rest of the computers are a pretty good deal. But of course you can build a computer yourself for cheaper. It just isn't feasible for most people to build their own computer. 90% of the population is still pretty computer illiterate (at least from what I see at best buy).
