I randomly bought an iPhone4 doing zero research on other phones. Two years later I got an iPhone5 because I could transfer all the apps and shit that I paid money for.. otherwise I may have got something else.
The Note2 is expensive, but looked cool, I guess. The screen was fucking big. All that Droid shit confuses me, probably because it's just not what I'm used to, so yeah.. iPhone if you want something fast, simple, and reliable. Siri is awesome. You hold the button and say "directions to <address>" and the gps pops right up. Say "scores of the <team> game" and it there it is. The talk-to-text shit works great, too. I use it while driving sometimes. Just say "text Mitch" and it pops up. Say shit and send it. I don't know if other phones have something like that, but it's convenient.
