Thanks everyone for your input. Please keep it coming!
We would use the USB for family photos & movies...we would watch them far more than an HD show. It'll be a while before we get a Blu Ray player.
Thanks especially for your answer. (If you have a long version -- i'd appreciate it too!).
Yes, our living room is really that long -- it's the front of a Chicago bungalow. The middle space is generally "play space", with the couch & TV on opposite walls.
Thanks for the starting price -- anyone else have thoughts on what size should be what price
