My wacom supports pressure , which is a very cool feature :D
But when you're using your fingers, you sometimes miss the hability to right-click.
Windows has a nice workaround: When I press the screen, the "click" event isn't generated immediately. Instead, if I don't move my finger for a few seconds, it sends a right-click event.
And, since it requires a few seconds without motion, it doesn't affect the ability to click and drag&drop.
I can survive without that on Linux, but that would be something very nice to be added in the future.
