Not sure if anyone is still interested. A few cons about the Nevo.

1. Loses WIFI connection every now and then, even if you set WIFI to never turn off.
2. When WIFI set to "NEVER" turn off, battery will last about 4.5hrs.(Beware NEVO SL will also crash every now and then and have to be reset by switching off on the side)
3. Control over DSM-320 media box very spiratic. Apparently Nevo are working on this. The idea being that the DSM-320 can be used as multiple zone breakouts for music stored on your music server PC.

If anyone has been able to rectify any of these issues, would be very interested.
