  1. Here’s a smart pen for paper note-taking you can buy on Amazon.

  2. WANT!

  3. These are sooooo expensive for a ball of fluff.

  4. I can recommend the book by John Vacca that came out a while back, but it lacks biology and chemistry problems to some extent. A website would serve as an online bank.

  5. Already exists, check out Rock Check. dunno if its any good though as unsure how it can tell just from a picture and some facts.
