Is there a LED HDTV that supports a wired qwerty keyboard? My mother-in-law has a rare medical condition where she is sensitive to electromagnetic frequencies (EMF Sensitivity). I'm looking for her a Smart Internet-ready LED (not LCD or Plasma) HDTV that supports a wired usb qwerty keyboard that she can use to surf the internet. I know Philips offers such TV's but you can only get them outside of the US. Does anyone know of such a HDTV? Thanks!
