I'm asking about the 15" MBP models. The i7 model is "better" in specs, but I was wondering if there were real-world issues the i7 has that aren't present in the i5. - Does the i7 have shorter battery life and a higher running temp? - Have there been significantly more i7 problems reported than i5? - Can the the 330M card actually make use of the extra VRAM in the i7 model, or is just a higher number to look good in charts? - Is the i7 MBP heavier than the i5???
