Interesting guys. Im in deep discussion with myself at the moment about the new Retina model and its good to see some good critisim.
As you say Matt C, the thinness is very attractive and Im like, "I want to have the best possible display and have the wow factor" but like many, Im not going to be using it for photography/Video editing so is there any real point?
Im a bit of an Apple novice and this will be my first Mac and from the research ive done it seems apps will take some time to migrate over to the new resolution while the main things like web browsing, youtube etc will see no benefits from the Retina. Would i be correct is saying that??
That being said, I'd still like a 15" but could survive with the 13". I should be entitled to a bit of discount as im starting my degree in in october so should i go for the 13" i5 and up the RAM to 8gb or leave it at 4 and swap the HDD to a SSD? Would 128gb ssd be enough seeing im not planning on loading the laptop with half the stuff my main pc has, i.e, Music, Programs etc? A ssd would make it alot faster wouldn't it? Also, is there much difference between the i5 and i7. Is i7 a bit overkill again for general use, browsing and word processing??
---or---
Should i stick with the 15" as standard - 4gb ram, 500gb HDD 2.3 i-7 and still be totally gobsmacked by its performance???? With student discount, works out about £1250 which includes apple care.
Hope i didnt ramble on too much.

Advice much appreciated!!!
Oh yea. Any sings of a 13" Retina model this year?? Im sure at some stage the retina will be as standard on the pro's??
