A hearty second to that. I'll repeat a post I made last night on a similar thread: Roku is a must. Incredibly easy to set up and use, and you get hundreds of free channels, many of them really terrific (for news junkies, for example, they have a channel that streams the daily half-hour newscasts from a boatload of cities. Very interesting to watch). I Heart Radio is also free, so you get radio from all over the country, as well. And Youtube has just been added to the free lineup with its bazillion videos. If you want pay channels like Netflix, you just add them from the on-screen “channel store.” And considering Roku is a one-time $40 purchase (sometimes less if you buy it reconditioned on Amazon), I can’t think of a better value. You have to have wi-fi, of course.
In addition if you travel much, a Roku Stick is great. Take your TV with you. I’m a WWII buff and YouTube is a must.
