ok, I have a telefunken tel7j and a computer with windows 7 updated today. I have an android phone, never had a problem with it, using it or connecting to computer. I've had too many problems trying to get the computer and the tablet talking to each other. I've followed the instructions in the booklet and searched the net. The fact that Telefunken doesn't offer any support says something but it's hard to tell what. Not sure what they were thinking here. I see problems all over the net and very few answers and fewers replies about whether the replies helped. I'm returning it for a refund. I'd recommend everyone else does too. Serves Telefunken right for putting out products without supporting them properly. I like android, probaly try a different tablet soon. When I first decided to buy there were few problems about this one but I suppose that's because they were so new. Wish me luck for the next one.
