I can respect that. I've personally haven't experience any lag with my previous Note 2, OPO, and currently my N6.I'm a huge Samsung fanboy, but even I notice the lag. The 3 seconds it takes for the task manager to open, or the 5 seconds it takes for the camera to open, etc etc. I don't think anyone should take it personally, and possibly some have more of a tolerance than others for it. What may be lag to me, is simply an app opening regularly to another.
But I also don't run tons of apps or widgets to begin with.
