I intend to move up to the Lumia 1330 when its released, from my current Lumia 1320. I've just got used to the 6" screen so I'm apprehensive about the speculated 5.7" on the 1330.
I moved up from a Lumia 820 to the Lumia 625 to the current Lumia 1320. So going down in screen real estate with the 1330 after climbing up to the 1320's widescreen, cinematic beauty!
