As fathers day approaches this month, my wife will be getting me a present. I was thinking about getting a table. Everyone on here raves about how good they are and how much they love them. So what is the difference between these two? Wacom - Bamboo Pen and Touch Tablet - Black - CTH460 Wacom - Bamboo Pen and Tablet - Black - CTL460 or if someone has a better idea for something in that price range.
