You won't regret making this choice! I am a bit of an Apple fanboy but I cannot believe how far behind the iPhone is compared to my Note 3. I'm even considering ditching the iPad and going Android Tablet too. Although I'm not giving up my Macs! There's just so much more possibilities on this platform, not to mention that beautiful big screen and awesome battery life. I don't miss much at all from my iPhone, maybe the iCloud for all my media, but there are workarounds, especially now I have ~100Gb of storage.
My next little mission is to root the phone, I have a lot of experiences jailbreaking iPhones but I'm a little apprehensive about rooting for the first time. One day I'll pluck up the courage!
Hope you're enjoying the Note 3 as much as I am!
