About this whole Stock Android thingy...

No offense, but Just a q, Why is it that you like Stock Android when youll just put a launcher and icon pack over it, doesnt really make sense since most of you say its because of the icons and launcher, but when you get a nexus, you just put some theme into it, kinda weird....just saying

(I myself try out extreme homescreen designs, but I was just curious bout this thing)
