I do not use Photoshop, but Corel Painter IX. Graphire Tablets... I use a Wacom Tablet, it's just like drawing on paper, but your art is digitally put onto the screen... so you're drawing normally, but instead of looking at the tablet you watch the computer screen. AT first, it's a bit strange, but you'll get the hang of it.
If you're really serious, you should deffinately get one: But they don't come cheap, they are very costly.

It was my big present for Christmas last year. It helps a lot!
So yes: Very easy to use once you get the hang of watching the computer screen instead of the tablet. Happy drawing!
