First off...what is rooting and how does it benefit my device? Second question...I have 300-400$ to spend. Is this the best tablet for the money? Third question...has anyone tried Tango Video Calls? It's another video call app. Does it work? and lastly...what are you all carrying these things in? I have yet to find a case. PS forgot to ask...I'm getting it from Best Buy, is this the one with the 1Ghz Snapdragon?
