Hello. I have been using my IPT 64GB for over a month. I have two questions: 1. While playing music, I pressed the power button. The screen was turned off but the music continued to play. Why pressing the power button did not turn off the IPT entirely? 2. Why there is no remote controller (from 3rd parties) that can turn on and off the IPT? As far as I concern, this is a very useful feature. Thanks.
