If you don't want to wait for LG's new TV you can use Boxee on your AppleTV now and enjoy Hulu (and others) in your fourty-something tv..
Ironically, the reasons to keep your cable provider moving forward will be news and live TV.
And this from the NY Times about CBS and TV.com:
"When the CBS Corporation bought CNet for $1.8 billion last year, it acquired TV.com, a Web site that had little to brag about except a valuable domain name. Now CBS is transforming it into a video destination."
