As someone that has been wavering between iOS and Android for a couple of years now (currently own a 4s and a Galaxy Nexus), I can honestly say that for me, it all comes down to one missing feature. If Apple were to add a notification LED, they would have me back permanently. Please Apple.. Add this on the iPhone 5! Until then, the Galaxy Nexus edges the iPhone 4s for me (just my opinion.. I realize many would disagree).
