So I got one to test out and then picked up 10 more to sell. The only differences are..
1. Box colour
2. Nova is built in. I got the login screen for Nova upon initial boot up.
3. The box is running the same software and interface as the tvonline 4.
4. For those who buy from sources other than Avov, you'll know for sure that there is a one year warranty (or close to) as the blue boxes are new. Buying red at this point could be old stock and substantially shorter warranty period.
That's it really, same specs as the red. In my opinion the interface is much nicer than the original red version.
