Hey, guys. I am a noob, so I apologize in advance. I have this question that I'm sure has been asked about 10,000x but when I searhced around, the best I could find was the same question as it relate to the late 2012 model but not the early 2013. I am looking at getting my first mac, and I want the 13" form-factor. I have heard and read a lot though, about how I might as well buy the 15" by the time I upgrade the 13" at all. I am wondering if the opinion is still the same now that the pricing structure and specs are slightly different with the 2013 update. I am looking at the getting the 2.6 i5 version for $1,599 (govt discount), but am wondering if I should upgrade that to the 3.0 i7 for $180. I think that is all I would do to it. The base 15" that would be the alternative is the 2.4 i7(quad) for $1,999, so I'm looking at a difference of $240. Not really that much I suppose when there is twice the cores plus the independent graphics card. So I certainly understand why the 15" is attractive, but I've had two 15" Dells and I'm ready to move on to smaller pastures. I don't need 15" for any reason and I'm going to be taking overseas with me to graduate school and travelling around with it a lot. I can't find any comparisons between the i7 dual vs i7 quad to see just how huge the difference is. Also, is it even worth upgrading the 3.0 i7 on the 13"? It doesn't sound insubstantial to me, but the last time I was really up on my PC tech was wen I was buying core 2 duos and all that business back in college in 2005 or 2006. I just don't know anymore. If I don't upgrade the top model 13", then the price difference is $400, which is easier to justify, but I only want to do that if I really won't be able to tell between the i5 and i7. I'll be going to grad school and doing mostly web surfing, email, word processing, maybe a light RTS game or two. SimCity possibly or Total War game. Watching movies... I would ideally want this to last me 4 years. If my piece of crap Dell can last that long, including going to Iraq with me and back, I will expect similar (or better) from a MacBook.
