Well, I guess technically I still need cable so that I get internet service.  However, I am cutting part of the cord.  I just bought this.
It is very tiny.  We hooked it up last night in just a couple of minutes and were watching Hulu Plus in no time flat.  The screen looks perfect and the remote is very easy to use.  I bought one that I can use with an HD television though I am using it on my huge glass flat screen television which refuses to die.  (There is a very nice Sony HD monitor waiting in the wings.)  If I feel like I need to use a second television, I can pick up the very bottom of the line, simple Roku unit for about $50 from Amazon. 
In the fall I plan to purchase an antenna to pull in local news reports.  Until then I can keep up just using the internet and my cell phone alerts me if there is any National Weather Service updates I need to know. 
Removing the television portion of my cable will reduce my bill by about $65.  The unit I just purchased was on sale at Best Buy for $80.  The Roku box nearly "pays" for itself with my first billing reduction. Comcast has jacked up my cable television bill for the last time!
