Well that's another problem with Android that I wanted to touch on: it's not trivial to try out different OS, which I think is more a fault of the phone manufacturers rather than just Google. The whole smart phone ecosystem is all about walled gardens. I agree about battery life for iPhone, pretty much everyone who owns one complains about how their battery doesn't even last a day. My Nokia X20 can last 3 days with light usage... Which I suppose makes up for the poor proximity sensor.
