I got a Wacom Intuos tablet for Christmas this year and it is really quite wonderful. If you do a lot of work with Photoshop it is a god send. You don't realize how much better it is to do creative things with a pen instead of a mouse. People often say would you draw a picture with a brick? I find it really helpful when making my thumbnails. I also use it in Adobe Premiere and After effects. Very effective and can be a lot of fun.
