I'm a freshman girl in college, and trying to decide if over the holiday season I should invest in an iPad 2. I have the iPhone 4 and I absolutely love it. My laptop that I have is a Toshiba and it's a 17 inch screen so it's pretty big and bulky. My campus is spread out so I walk everywhere. I was thinking the iPad 2 could be a good investment to use in and out of school. In school to take notes (maybe get the apple keyboard that goes with it?) and academic stuff like that. Out of class of course for facebook/twitter. I don't play on playing too many games, just words with friends. Also, I don't plan on putting any music on it. Should I get the 16 GB? Also what is the best cover? Thanks!!
