I'm about to start my first year of college as a business student and I'm currently torn between the MBA i7 dual-core/8GB RAM/512GB SSD and the rMBP i7 quad-core/8GB RAM/512GB SSD. I'm going to need to be running windows frequently for the Microsoft Office programs but I also want to be doing some light video editing (720p) for my video log. I also want to try dabbling in the stock market and am going to use a market analysis tool. However, I am also going to be almost constantly carrying my laptop with me, so I am wary of getting the retina. I would definitely be getting the air if it had a quad core processor, but that's not the case. I guess my question is, will the dual core i7 still effectively run these processes blazingly fast? I'm not going to be running them all at once, in fact I'll probably only be using these one at a time. I need this laptop to last me 4 years so I'm really questioning if the dual-core will see me through, but it still is an ivy bridge. Any thoughts? The videos I'm going to be editing are not going to be any longer than maybe 5-7 minutes each. My real concern is the market analysis tools and running the microsoft office tools via boot-camp.
