I've ordered one and have got a buyer for my iPhone 5 already. The screen would need getting used to at the beginning however as you get used to it you won't think it's that big. Then you will look at an iPhone and wonder how you could have used something so small. I've researched a lot to do with this phone and it's incredible. The multitasking alone is great. If you don't know and think I mean multitasking like on the iPhone then it's completely different. You can watch a video and then go into your messages and send a message whilst watching the video in a smaller screen.
The specs and power of this phone are second to none. I'm pretty sure in the comparison to most, if not all, tablets it exceeds them. I am used to having a Jailbroken iPhone and constantly was installing tweaks because without a JB the iPhone is flat and boring. I've had my iPhone 5 since launch and I am bored of it. You can't do anything on it. I used to be on my iPhone 4 all the time, every minute of the day but since the iPhone 5 has no jailbreak I barely use it. Android is wide open. You can change the themes, OS, overclock, etc, etc.
I've not got my Note 2 yet but already I'm a big fan. And being honest I hated Android. It wasn't anywhere near as good as iOS however they are pretty much on par - if not exceeded (Android) now.
