I don't think anyone expects a phone camera to be as good as a dSLR +steven baks
but better optics & sensors in phones will always be a selling point. It's the reason I continue to use Sony phones.
On that note, the next Nexus 4 won't be the amazing camera they tout it to be if it doesn't have a dedicated camera button. Another reason I'm still with Sony (and won't be upgrading to the Xperia Z)
