Lagging hardware? The Lumia 930 (Icon) and Lumia 1520 both have Snapdragon 800s and 2 GB of RAM, as well as 1080p displays. I know it isn't a Snapdragon 801/805, but those are relatively minor revisions to the Snapdragon 800. The Samsung ATIV SE has the same specs as the Lumia 930 essentially, which places it somewhere between a Galaxy S4 and Galaxy S5 in specs - not to mention it looks identical to them.
The camera hardware in the 930, 1020, and 1520 puts just about every other phone to shame. Whether or not you like that platform, I don't feel it's fair to say it's bad because of hardware.
