I pre-ordered my POD Go back in February and received it in early May.  In the few weeks I've had it it has frozen up at least three times forcing me to turn it off and back on. Once it froze in the initial boot up screen showing the software version and at least twice it has frozen in player mode with the individual lights on. Repeated pushing of the buttons accomplished nothing, the volume pedal did nothing for the sound...it was completely locked up.  I had to turn if off and back on again.
