It's an illogical buy, through and through. Yeah, Windows sucks, but if you know what you're doing you don't exactly need to run heavy anti-virus crap and even when you do, an i7 620QM quad core and a new video card will still kick the living crap out of a C2D and 9400+9600GT setup, for less money.
I am 100% Apple, but what strikes me as odd is that in general the users go against all buying logic that makes any sense. What you're saying makes sense up to a point. Right now, there's a biiig generational gap, which would be fine if Apple wasn't charging the same price they were 8 months ago.
I'm not sure how it doesn't bother you to drop two and a half thousand dollars on something that will be updated within the month, and will be updated to significantly outperform your purchase for the same price. You are getting no value out of the buy. I'm curious what you not-waiting folks are using your computers for, where a speed and value increase does not matter.
It's illogical and foolish to buy right now.
To put it simply, many of us, in-fact most of us do not need this significant upgrade in processor speed! The current model provides more than enough wack, even for top end software like logic pro which I can say runs smooth even on a 2GB RAM, 2.8Ghz core duo. Not only that, the new processor update may prove unstable and need perfecting, unlike the current. As for the money I benefit from student discount.
