I don't understand this. If I don't care about specs, I own an iPhone. If I care about personalization, I buy a case for it, which allows me to swap out the appearance of my phone far more often than my contract. And because it's a case, my penchant for bizarre colors won't effect my resale value.
(And although many cases are lame, there are some pretty damn cool ones out there for the iPhone.)
Or, to sum it up with more direct competition, the Galaxy lets you peel off the back cover and put on a new one at will.
And what happens with insurance replacements? I'm going to assume it won't be covered by AT&T/asurion. Of if it is, what do they send out as a replacement? Your green and blue with purple phone or the standard black?
