On the other hand, it's distracting because without an index system (I start each notebook with two blank pages trying to index the contents; every other page has a number) it's easy to get lost.
I use a smart pen that writes in a notebook, but also stores everything I write in memory. Every month or so I export the content of the pen to my computer via Bluetooth as OCRed PDFs. This is because my boss often asks me to account for time I spend doing different things, and I can quickly search the PDFs.
