Still waiting for my install on Tuesday, but I had to plug it in and play with it. I wish there were an HD demo channel (if there is I couldn't find it) but otherwise it looked pretty good.
I did stumble across one possible bug or perhaps "feature". Since it was not activated yet I didn't bother to plug the phone line in. After it downloaded the software and I played with it for a while, I accidentally powered it off. When I powered it back on it prompted me to plug in the phone line. i could not get that display off of my screen. It was FORCING me to plug in a phone line. Perhaps this is intentional (if so, I'm guessing the $5 charge is no longer relavent). Once I plugged the phone in, it got past the prompt and it was fine. I tried to repeat but I'm guessing similar to the 522, it will only check once per day at first power-up.
