I just got my WonderMedia WM8650 tablet today from ebay. I bought this cheap tablet to take to work. I was hoping that it would do what I needed it to do for work purposes. I really like it except for this one major problem; My tablet does not have a calender in it. When I click on the calender icon, it wants me to set up an Exchange account? I tried a few other calender programs but any time I try to add an event, I get an error saying no calender. Any way to get a calender into my tablet?
