Interesting new tablet out there. It comes loaded with Android 4 Cyanogenmod 9. Nothing to special about that but the manufacturer is tossing Ubuntu on it as well.
They will (or do) make all the source open (or as much is possible).
Seems really promising to me.

ZaReason seems to be a really cool company.
