Unless the new displays come with both, I think 3D (sooner or later) is going to take a back seat to things like Facebook, Youtube, Hulu, etc. I'm not as big of a TV watcher as I am a music listener (so take my comments with a grain of salt), but I really like how some of these new displays can access apps like your basic smart phone can. I would take those features over a 3D TV/glasses any day of the week.
Can you imagine, if these new sets don't already have them, having a remote that had a touch screen on it where you can manipulate the media (finger scroll, pinch, etc.) on the remote and see it on the TV? Or better yet, maybe connect to your phone via WiFi so you can send picture and video content from your phone to your TV for viewing? That would be pretty cool.
And yeah, $2800 for a 20" display? Pass..........
