Well, to add to that legend here is another black box called the Roku.
|The Roku little black box.|
Set up could not be simpler: plug in the box to your TV's video and audio inputs, connect to your wireless internet and that's it! You now have access to Netflix, Hulu Plus, MLB, NHL, listen to your music on iTunes and thousands of other sources provided to you instantly. Some, like Netflix and Hulu Plus charge a small monthly fee, others provide their content for free and more providers are added all the time.
Lastly, the cost of the Roku is the greatest, best shock- Full 1080 HD television for under $100. Plus, a basic Roku with standard definition and fewer of the bells and whistles can be had for $69.99. If I were you, I'd pop for the extra $30 and get the best box with the most stuff. Amazon has all of the flavors of Roku for sale and you can find it here.
Ironically, the only reason you'll continue to need cable is for the internet connection to keep you Roku well fed.
