Roku is awesome.
It's a streaming device that you sync up with your modem/router and it has several "channels". You can watch your Netflix instant movies (must have Netflix acct), Amazon Instant Video (which is basically PPV via Amazon---again, you just sync up your Amazon acct to Roku & you can order them right off TV), HBO GO (if you have HBO), Pandora (if music via TV is your thing), Hulu, Flixster (to watch previews), a Disney channel, epix (some decent flicks free & on demand), and Crackle (similar to but not as good as epix).
They've added a handful of channels in just the year I've had it. I don't think it gets enough props. Best $60-$70 you can spend to enhance TV watching. And Amazon's new release movies are typically cheaper than your cable PPV.
