I have a gTab running VEGAn 5.1 - its great. Fast and fun. One thing that I am not understanding is why the device keeps losing the current time and date. I have not notice if it only happens when the battery dies, or exactly at what point it changes. Not matter what, I would expect there is some sort of watch battery type of thing like the CMOS battery in a computer that keeps time when the system is off. Does it not have one of those?
