I am in high school, and need something to get a fair amount of school work done on, lots of surfing the web, check my emails, play games, watch movies, and take it with me where ever I go. I've narrowed down my choices to the 64gb iPad 3, and the 256gb MacBook Air. What would be better for me? I know that there is quite a bit of a price difference between the 2, but I'm willing to pay it. BTW; i have 2 windows 7 desktop computers at home.
