I'm starting medical school in about a month and need some advice on what to buy. I currently have a 2012 model MBP. My main uses are going to be reading and annotating large PDFs of textbooks, sometimes streaming webcasts of lectures, listening to music, and surfing the web. I've been debating what to go with. I was looking at this on the refurbished site: http://store.apple.com/us/product/F...nch-macbook-pro-24ghz-dual-core-intel-core-i5. It's a rMBP 2.4 GHZ with 8GB of RAM and 256GB of flash storage. 1. Would this be sufficient for my needs, especially streaming webcast of lectures and downloading, reading, and annotating large PDFs of textbooks? 2. Do I have anything to worry about it with it being from the refurbished site? 3. Should I look at MBA? I was originally going to go with the MBA before finding the refurbished site and I figured the retina display would be nice for all the reading I'm going to do.
