And, when everything changes again (media formats, containers, new services, etc.), it's much easier to handle buying a new $100-$200 box to attach to your non-connected TV, than to buy a new $1000-$2000 TV.
Nope, the TV just needs a Firmware update to upgrade it to the latest standards and codecs. My Sony LED/LCD HDTV has had 2 major firmware updates in the last Year. The updates sped up operation plus Sony even added new features and services.
