I will be in the market for an iPad soon. A main use will be to watch videos encoded from standard-def DVDs. However, I'm wondering if the iPad 2 or iPad 3 will be better suited for this? Given that max DVD resolution is 640x480, will it look worse on an iPad-sized Retina display than on the current iPad 2 display, because the native resolution difference will be so much greater? Alternatively, a friend suggested DVD would look better on an iPad 3, because any pixellation will much "finer" with the smaller Retina pixels than on the larger iPad 2 ones. Appreciate everyone's thoughts.
