Saw one where a guy had 2 videos off his sd card playing at the same time with 4 youtube videos in different tabs all playing at once doing the same setup.

Little lengthy but a good watch to show how much the Note 2 can handle all at once.
That was crazy that the videos had no trouble playing. I am seriously reconsidering carrying my laptop around...
on another note, lol cats and lettuce.
EDIT: Holy crap, did not know you could hook up a USB thumb drive like that.
