Hey guys. I'm going off to college in the fall and am planning on buying one of the new MBP's. I don't know which to choose. It's either the 15" with i7, HiRes Glossy, and 7200rpm HD, or the 17" i5 I would much rather get the 17" but I don't know if it is worth it to upgrade it to the i7. The other day I discovered that apparently not all core i5's and i7's are quad core and that the MBP's use the dual core i series. so thats not a huge deal but ive heard they are so similar and i dont know if its worth the extra $150 (cant remember price off the top of my head). Any info would be appreciated.
