Taking notes and sketching things is so much easier with paper so I pose the question. What "smart pens" are on the market now.
I have seen some like the livescribe and the equil but don't like that you have to buy special paper or attached a device to your note book for it to capture writing.
Are there any smart pens out there that can capture writing and sketches with out the need for special proprietary paper or bulky clip on sensors. Some thing that is simply a pen with Bluetooth sink to a mobile.
Let me know what you are using.
