Need a little help deciding what to keep
So I have a nice 2011 macbook pro 15" quadcore with applecare for 2 more years. I bought a white ipad 3 16gb on craigslist over the summer for 300 with applecare until march. Then just this past week i bought a 11" macbook air on craigslist for 450 with a 1.6ghz intel core 2 duo with 4gb of ram, a 128gb ssd, and applecare until november of 2013, and a couple of other goodies came a long with it. I bought the air with the intention to resell it on ebay, but I really love it. I didn't think that I would like it since it is so small, but i do. So I need help, I really should get rid of one of the three but don't want to, which should I get rid of? I do a bit of spreadsheet work, writing, a little bit of video editing, and hard drive ereasing/reformatting fairly often on my 15" pro. I feel like i should keep that. Beyond that I mostly do surfing and watching videos that i use the air or ipad for. what do you guys think?
