For folks who are currently subscribed to Yamaha's internet radio, I'd like to know your experience with it.  I haven't seen any Amazon.com-like review on the internet about it.  I'm thinking of upgrading to E3 or getting the DKC-850 to replace my unit.  The E3/DKC-850 desire is driven for the most part by the appeal of internet radio, and of course the convenience of USB.  I have Sirius satellite and find that selections, over time, tend to repeat to a point where you'd know you're listening to Sirius when you hear song selections/groups being played.  

Wondering if such is the case with Yamaha's internet radio? What else do you like with the internet radio aside from what's advertised as its selling points?
