I plan to get a 32GB iPod Touch in about 2 weeks and I want to buy some apps now. Can I buy the apps before I get the Touch? I think the apps that I want are on sale right now or something because the prices are like $1.99 where they should be more. Also, I plan to buy a Macbook early next year, but right now I have a Windows desktop. Will the apps transfer over like music? Sorry for the dumb questions, this will be my first iPod Touch.
