What made you decide that the difference between the i5 and the i7 is worth the extra cash? I thought they were supposed to be not too dissimilar.
Out of interest for myself, congrats on your decision!
Personally I always look at it this way: right now there isn't that much of a difference between the i5 and the i7 —*unless you're doing some specific stuff, or really want to fastest available. So... by the time the i5 gets too slow for what you'll be doing in the future, it doesn't mean that everything would still be fast if you'd gotten the i7. It'll also be too slow, just a little bit less.

I am so tempted to do the same, I bought the 17" I5 Glossy.
Now, I am sure want the I7 but I'm not completely sold on the Anti Glare.
Maybe it was just the calibration, but the Matte looks so washed out compared to the glossy at the apple store. Plus Im in the camp of not a fan of the silver bezel, but thats not a deal breaker I just like the look of the black bezel better.
I went to the Apple Store today and if I want to upgrade (no restock fee, cool manager!) I have to get the I7 with the antiglare oppose to the glossy, since they wont stock the glossy in the I7.
So my options are keep the I5 Glossy or i7 Matte.
Edit: By chance how is the heat comparison? I7 much warmer than the I5?
