Picopad arrived today. The pen is very small, but it does write. The pad consists of some small sticky notes.
I have removed my wallet pen, which I kept in the middle crease of the wallet, and my own 3-inch-square sticky notes, which I kept with my paper dollars. Later on, I might bring back the wallet pen but keep the Picopad for the conveniently packaged sticky notes.
I usually have my PDA with me and I use Jott and love it. There are still times that I want to write a note. I didn't use my wallet pen a lot, but it sure was nice to have when I needed it. The Picopad seems to offer some incremental improvements over my existing setup.
