well, modern flagships require deeper pockets anyway so.........
I had Dell streak back in the days and I was claiming that's the future and everybody was LOLing and telling me that I'm crazy. Now I have XZ2 which is roughly the same size but with bigger screen.
I was always going for the bigger screen so I was never in a situation that I had to jump from 4" to 6" because my "compact" died. It was always a choice.
At some point I had galaxy tab P1000 and I used that as a phone
Now, that was not pocketable but after experience with so many different sizes I know that 150-160x70-80 mm is fine for me. Going back to 4.5" of Jolla 1 was more of an issue than it was a Streak for the first time.
