Samsung has wireless, Sony is optional dongle i believe.
Samsung does USB recording & playback, Sony does'nt as far as i'm aware.
Both are 3D, which you say " Not fussed about 3D" so i would suggest a demo to see which has the best 2D picture in your opinion, bearing in mind that you are the one going to be watching it. Either way thats a good price for both of your selected TV's.
