About two weeks ago I purchased: non-retina MBP - 13-inch: 2.9GHz 8GB memory 750GB hard drive and today I am totally confused if I should return it and get: 1. 13-inch MacBook Air 2.0GHz Intel Dual-Core Core i7, 8GB memory 256GB Flash Storage or 2. 13-inch MacBook Pro with Retina 2.5GHz 8GB memory 256GB flash storage or 3. Keep my non-retina MBP I recognize the $$$ difference and willing to go up to spend on rMBP 256GB 13-inch if that is the best machine to buy. 15-inch is not an option for me. The use of the machine is lot of web browsing, connecting to PS3 to wireless stream video and some video/movies viewing on the laptop itself in addition to Mac Office for documents. No advanced video or photo editing or gaming. Please suggest as I have to leave US in a week for a long international trip and want to change my machine before that. Thanks in Advance!
