I have a stylus for the iPad but I stopped using it after the first few days.The fact is that, until there is a digitizer on the screen, it is very difficult to get precision, especially for drawing. There are a lot of new styluses (stylii?) with a lot of pressure points, but you still get a noticeable lag when using them. An iPad with a Wacom-like digitizer is one thing I really want. Whether it happens or not is up in the (iPad) air.
