I bought the tablet at Microcenter a few days ago (Merry Christmas toy early for me!) Seems to work OK, as advertized. The documentation is awful, no hardware or software user guide. For instance, it has HDMI out, but I don't know if audio is available. I added a 16gig card, but I don't know if I can move or install apps onto the card. Anyone else farther down the learning curve?
