I am looking to get either an iPad, Macbook, or Macbook Pro. I will be using for mainly schoolwork, web, etc. I am leaning towards the Macbook, since they're more of a computer. So here are my questions. 1) Can the iPad get the job done well? 2) What is the main difference between Macbook and Macbook Pro? 3) Are refurbished Macbook Pros any good, and will they get a free update of Lion? 4) Any other suggestios? I'm going to get a 13.3 inch if I get a Mac, and will wait for the next gen iPad if that's what I get. I already have an iPT 4. Any help would be greatly appreciated.
