All, You probably already know this, but it seems like the Macbook Pro i5 is a better computer than the i7 for many users. They both have large performance gains over the Core2Duos, but the battery life of the i5 is significantly better in real world use. I purchased an i7 and my friend purchased an i5 15" Macbook Pro. We both have the hi-res antiglare screen and we do the same type of work... web design with Dreamweaver/Fireworks CS4. We don't run any background apps except for quicksilver. We also both use 160gb Intel SSDs. In the two weeks that we've had the machines, we've consistently noted that the i7 machine is warmer and that battery life is lower (by 30 to 40 minutes). We even switched machines using a blind test methodology to see if our usage was any different. Whatever the performance gain is with the i7, we could not perceive it in terms of our use. The battery loss was very noticeable... it was the easiest way either of us could tell who had the i7. I'm a performance freak. Despite what the benchmarks tell me, I can't see the benefits of the i7. Unless we were gamers, I don't think we'd notice the difference in graphics memory. To make a long story short, I've put my i7 on eBay and got myself the base i5 model. It has only been two days, but the battery life difference is clear. Hope this helps anyone sitting on the fence. It could save you some cash.
