For years Apple has wanted to get closer and closer to the "appliance" model for their products. They are targeting consumers who's gut instinct when it comes to fixing their computers is to call a "geek". These consumers just want the damn things to work and would rather not worry about upgrading it over time. This is of course very unattractive to the hacker crowd, but they make up a much smaller percentage of the computer using public now than they did 20 years ago.
