We got a Roku for Christmas.
I love it.
It brings the joy of the internet to my tv screen.
Netflix and Hulu at a moment's notice? Check!
Pandora singing away sweetly at our next dinner party? Absolutely!!
For us (and we understand, perhaps not all), this little device is a great way to avoid the time-suck that cable sometimes was for us while allowing ourselves a little bit of relaxation in the evenings or on the weekends.
TV (and movies and music) by choice ... not death by a thousand channel changes.
