I use the BOOX NoteAir, just to keep from having a dozen scattered notebooks and having to replenish the paper/ink supply. I use it just like paper. I don't do any handwriting recognition or anything, and at most will split ideas off into their own notebooks. Personally, I've found that it is the act of writing things down, more so than the act of looking through notebook archives, that helps me with retention and creativity. The VERY IMPORTANT THINGS are kept on a whiteboard I look at multiple times a day, because I WILL FORGET dates and appointments (and I'll forget to put them into an alarm on my phone, and I'll dismiss those alarms multiple times and re-forget) no matter how critically important it may be. So the whiteboard keeps those items literally in my face.
