I felt the same way when I first purchased my iPhone 3 I was so excited to finally own an iPhone after having the Original Incredible and then the Droid X the iPhone was really limited and well like you said boring.I'm at the point where the Note 3 is getting to be too big. The Note 4 will be my last phablet that I buy unless they kill the home button and go with onscreen buttons.
The i6+ that I have surprised me at how big it is. I hadn't seen any comparisons before it arrived at my doorstep and the fact that it is longer than my Note was baffling.
I also own other Apple devices, but haven't owned an iPhone for a few years. Oddly enough after getting one the experience hasn't changed. iOS is boring.
What I think is interesting the iPhone 6+ has the multi window feature,,SO will Samsung go after Apple and sue them for using their idea ???
