I'm sorry, but is the submitter fscking insane? I rely heavily on handwritten notes all the time. So does every college student and scientist that I know. Note that I'm talking about extremely tech-savvy people here, who often DO own an iPhone... but they are fundamentally useless for taking notes.
Taking notes, of course, is not the only writing one does, but it's a pretty important thing. Writing serves a a communication medium to others, but equally serves as expansion of short- and long-term memory for ourselves. I have yet to meet any GUI interface that has the flexibility of a pad of paper:
- Effortless data entry.
- Figures, mathematics or other non-ASCII input are faster than any other technique (and likely to remain so)
- No learning curve (for people past 6th grade)
- Bookmarking, fast page finding.
- No limit to page-space viewable at one time
-Needs no recharging, syncing
- Not a target for theft
- Light and comfortable in the hand
- Cheap, reliable components
- Easily backed up by photocopier or scanner
The only downside, for me, is it's a little slow for pure-text entry, and it's sometimes hard to read by own sloppy writing. But that's just user skill, not the fault of the technology.
