I originally wanted an i5 matte but I couldn't wait any longer for it to arrive via the mail so I bought it yesterday when they got in stock at the stores.
i7 is overkill for what i do, but i sold my previous mbp for so much dough I just went for it. Now it's done. the +$300 from base to high end is better than the opportunity cost of me being without a functional computer for another week.
if you're getting i7, $150 extra isn't really that big of a deal for antiglare high res if you want it imo (although I'm not happy about this additional apple tax -- 1680x1050 should be free and matte). Otherwise, you'll regret it later.
