I am more than likely going to choose the Sony Xperia S for my next smartphone, but im also considering the HTC One X. The Sony Xperia S looks as if it would be more than able to do everything I need (I dont push my smartphone to limits, root or any of that stuff), but I am also thinking about what the future will hold and obviously by this time next year Quad-Core will be in full swing (im guessing).
So I guess I have a few questions which all relate to the same thing. What is Quad-Core used for? Is there much of a difference between Quad-Core and Dual Core? What does Quad-Core do that Dual Core doesnt?
