So I just went and looked at Macs at Best Buy during my lunch break... I am pretty much sold on a 13" Pro now.
Even though I had looked at the specs before, I didn't realize that the weight difference between the 13" Air and 13" Pro was only
half a pound. Really, that ain't nuthin'. I picked them both up and seriously couldn't tell a difference.
Also, there was a difference with the Retina display. There wasn't a *huge* difference, admittedly, but I could still tell. Since I do my studying almost exclusively on a computer screen, it will probably be better in the long term.
I like the fact that I can get 16GB of RAM with the Pro and a better processor. As far as longevity is concerned, I think both of these things will play a nice role in making my computer stay super fast for the next 4 years.
The difference between the 13" screen and the 15" screen also really isn't
that much. (Yes, I sat one on top of the other and compared.)
I'm used to using a 15", but I don't think the change will take that much adapting.
True, the Air has better battery life. Since I'll be maxing out my computer (except for the 1 TB memory... seriously, I couldn't possible use that), I'm sure I'll get less than the reported numbers. They say the 13" Pro can get 9, but I'd say that 5.5 hours would be more realistic if you are doing a few things at once (Internet, word document, etc). 5.5 hours is plenty for just about anything I can think of, though!
So... my advice is to go look! I was really favoring the Air, but not anymore.
Disclaimer: Of course, all of this is contingent upon the Air
not getting a considerable upgrade in the coming months... Hah! If it does, it might be back to the drawing board.
