okayyy. so here's my problem. I'm going to college soon around end of july. My parents promise to buy me a Retina MBP and I gotta move to another town that near my college. I'm currently using a Mac Mini. I decide to sell it off and add a little money for a portable device. I'm thinking, should I buy a iPad with 4G or Macbook Air 2011 or 2010 low end. I don't think i'll be lugging a two thousand dollar laptop everyday in college, if I don't have my IT class in that day. I hope to bring something light. I will be doing some heavy internet browsing or record down my note on it. Is ipad capable of doing my job? and im concern about battery life too. Which one is better? MBA or iPad 3? I own an iPad first gen but it's too laggy to do my things on it so I will give it to my parents, still usable though.
