If I have a Bluetooth keyboard at my disposal, I can take out my smartphone, pair & connect to the keyboard… start an email and start typing notes in 30 seconds or less.
I am typing using my AWK right now. This is almost a full-sized keyboard and I can type pretty quickly with it. The phone also has a camera so I can take a picture of handwritten notes, or notes on a board (white/black) if necessary. When I send the email, a posting is created with my notes and any images that I attach to the message. Those notes are then available on any device that is connected to the Internet. This is not difficult to do, but it does require intent to practice the way that you want to perform the task.
