I have an iPad mini and a 2010 base macbook air. I am going to college in a few months and was thinking about using an iPad for textbooks. I don't want to spend too much on apple products this spring, so I have 2 options: 1) Keep iPad mini and Macbook Air and also buy a retina iPad 5 (when it comes out) 2) Sell MBA and use that money (plus the money I would have spend on an iPad) to buy a rMBP and keep the iPad mini and possibly use it for textbooks (but I am afraid the screen would be too small) so with option 1 I end up with MBA, iPad and iPad mini with option 2, I end up with rMBP and iPad mini. Which seems like it would be the best for college? I am somewhat leaning towards the first option if only because I don't have to worry about selling my laptop and possibly being without one for a week or so while the new one is delivered. Any help would be much appreciated.
