I wasn't just repeating what they said in the store
The applications I was referring to were the movie maker, dvd maker, garageband (I know it isn't the best, but I didn't know exactly what he needed. I don't make music), and the like. And the other stuff, you actually can buy. Audio, video, photo, it's all better on Mac. That isn't pure regurgitated store-clerk fodder, that is pure hard fact.
Oh, and you can right click on a mac. They are coming programmed standard so that a right click with a regular mouse equals a control click, so you don't have to go through the agonizing two minute process of assigning a button to a certain action.
