I have the express version of the Mini Tablet and whenever I turn on the WIFI connection, the tablet becomes very slow and unresponsive. It's to the point where just trying to type anything on the keyboard is problematic at best. Anyone else with this tablet: Is this normal? Is there anything that can be done to improve the performance so this is less of an issue. I haven't done anything to it (rooting, etc) yet, mostly because I'm a little wary of tampering with the device, but this problem is my only major complaint about what is, otherwise a very nice little Android Tablet for the price. If anyone has any suggestions, I would be more than grateful. I'm aware that there is a 'better' version of this device and if this is a problem inherent with the lower-end version, then I'd be interested to know how well the better version operates.
