I've just got this second hand "Wonder Media WM8650" tablet and am very happy with it so far. Much better than I expected. The first problem, though, is that the previous user's gmail is still in the tablet and appears as the default email name in various places, and even seems to still download 3 non-controversial emails of his. When I try to remove his email in "Accounts and Sync", I get a message that it is required by some applications and that the only way to remove it is to take the machine back to factory default. I don't really want to do this until I'm sure what I may lose. Is there no way of gently removing the address? I don't mind if any paid for apps disappear. I've entered my email address as well and that seems to work - for example I can sync up to my Google calendar.
