I picked up an InkLink last weekend, and love it. In my opinion, its much more versitile than the SmartPad (I had a smart pad for my palm, it never worked well). The InkLink and SmartPad use the same PPC software, which works nicely on WM2003 with no problems. I only wish they had the option to import forms into the software and fill them out as you fill out the form on a clipboard. That would rock.
I'm using it for the classes I'm taking this semester, as I've grown weary of typing on my laptop (and notice that I surf mindlessly way too often while in class) and need to be able to sketch easier while still maintaining electronic copies of my notes.
Best of luck, I hope your SmartPad is as awesome as my InkLink.
