Two updates? The iPhone 4 got more than two updates? In fact I think iPhones get around three years of support/updates and that's around 2 years more than what I got with my Samsung Galaxy S2..
Plus you can't walk into a Samsung shop or even an htc shop and ask for help..
I'll admit tho I am considering giving android another go next November
That's not me saying I hate iOS...far from it actually, I love it because it is well refined and nice to look at. Apple do fine tune their os much better and fir me having iTunes to manage my music is far better than clumsily doing it on a phone screen!
Android has its pros so I'm not going to start slating one over the other, android lollipop does look fairly promising from what I've seen on the nexus 6 anyway.
