Except both of those things are magical stories made from fairydust. Vita's don't get burn in unless miss treated i.e. pressing on the screen to hard for to long and OLED lasts just as long as LCD it just starts to degrade in colour quality slowly but STILL looks better then LCD. Anyway justify a 2K to yourself whatever way you wan't, ill stay far away hopefully the 3rd revision goes back to OLED but i doubt it.
Pushing the screen too hard isn't burn in....
