I have the bamboo fun - which is a great tablet for Photoshop - but the touch features are not so great. Even under Snow Leopard I found that the Magic mouse worked much better. The drivers have not been updated for Lion and therefore I found that I had to purchase a Magic Trackpad to get the full touch effects that I have on the Macbook Pro with Lion.
I have to say that I like the angle of the magic trackpad better than the wacom, which is flat. But I do also have my mouse next to it.
