Handwriting hurts my wrists. My handwriting became super sloppy after what, like 40 years in front of a screen. Can't index or search my notes. I had one of those pens that record everything using a camera on special, dotted paper, but no OCR can process my writing, and you need special paper.
But yeah, the idea seems interesting. I like dedicated devices these days. It have to carefully think about what I'll be doing, pick an activity and then venture out to do the thing, packing the dedicated device that is suited for the task. I'm more focused that way, more productive.
However, that device here is not what I am looking for. Tiny keyboard, non ergonomic, colors too flashy.
