Got an iPhone 5 on launch day and returned it shortly after. Besides being taller, it's pretty much the exact same phone the past 2 years. iOS has become stale and boring with little no innovation. I also hate the way notification center is implemented on the device. (If it weren't for jailbreaking, I don't know how I could've managed).
With the Note II, besides the screen, expandable storage, battery, SPen features, etc, etc.. I'm able to customize the phone to fit into my daily life. Calendars, appointments, emails, tasks, notifications, all configured the way I want. With the iPhone, you're forced to adapt to their limited features and options.
Its interesting how when iPhone users switch to Android, it's always because they want a change and feel iOS has become boring. When Android users switch to iPhone it's usually because they want a phone that actually works. They either have one that lags, has problems or in my case, just tired of watching other phones get updated while their new phone sits on an older version of Android. You never hear of someone getting rid of their iPhone because it lags or doesn't work right.
