Hey friends, I need to buy Pen-tablet for my office work. i need it to create handwriting documents or handwriting recognized documents to take notes in the meetings and then can input to my computer after wards. I am confused by the options available. Tablet PCs are costly. I don't need that much functionality. Pen-tablet has so many varieties, like Capacitive, magnetic, Optical. Which brand I should choose ? Which Model ? Can you people Help ?
