...but several of them weren't.
I used to switch phones every 2-3 months (selling quickly after release makes such frequent changes financially possible if you know where to look), but with the Note 2, that's changing. There's nothing else that even remotely interests me at this point, and there doesn't appear to be too much on the horizon that will either. This is the first smartphone that I've ever been completely happy with. The Note 2 is the total package and then some. The next phone I own will probably be the Note 3.
