You know, the vast majority of people (millions of them) are not aware of XDA, quad/dual core, weekly upgrades etc. For them what matters is the default experience must be nice. That's what Samsung has focused on.
I can bet many buyers will be more interested in the automatic Facebook tagging vs camera sensor no matter what we think, that's just what the market is these days. I can see why Samsung chose to please them rather than the hardcore people. What is surprising is they didn't spend any time making the phone pretty.
