I had a device, it is still here somewhere, that was an A4 electronic pad, on top of that you inserted a regular A4 linear note book and wrote with a pen that had these small ink cartridges and the rest of the pen was a transmitter to the underlying pad. Everything you wrote on the pad was saved in memory, there were buttons you had to press when you ripped of the paper and started a new page. It had some IBM software that came along with it.
The thing was that it could handle handwriting recognition for Japanese, the characters are written in a very specific order, but it really had problems with alphabetic writing. It never caught on, partly because the pen lasted such a short time.
Once you finished writing you connected it to the computer with USB (proprietary cable, another no-no) and uploaded to the PC.
