well, you're mistaken -- i wasnt customizing it to make a point. i was displaying the exact mac i outfitted a month ago (actually, cheaper, because i probably added some stuff). that said, the upgrade to 3.06 ghz is definitely not worth it. still, that's $2599, when i wouldn't go over $1499 for that model at the moment. (of course i realize in this instance apple can't sell it for that low & that's just me, mostly because i want updated processor architecture + gfx card). but $600, say, is an awfully hefty premium for OSX + aluminum siding.
+higher quality led backlit display
+double battery life.
Based on the number of MBP's selling you are woefully underestimating these features value to consumers.
Personally I would pay a $200 premium for OS X alone over Vista or XP.
