Have you ever tried to use a computer at an Office Depot (or Office Max, Best Buy or Staples)? They have them locked up with some marketing screen saver. Even if you can start to use it, most of the time they are not connected to the internet.
Go to an Apple Store. Aaahh! Any computer is ready for you to — well — actually use it. If you scout around the store, you will probably find a model that has your favorite program already loaded on. (Well, sorry to say — none will have Windows Movie Maker or Real Player loaded.)
Just more evidence that Apple means for humans to use their computers.
