The longer I have the iLiad the more I use the note taking capability. I use it even for shopping lists. Helpful when you get stuck in a slow checkout line as then you can flip to whatever book you are currently reading
The pen does feel slippery and does take some getting used to. I have used Wacom tablets when working in Photoshop for 7 or 8 years now and that also took a while to get used to. I don't consider it a problem.
I never thought of adding templates. Great idea, how do you do that?
