What's nice about it is the size though. That's the novelty of
   it and I'm hoping they make it cheap enough to distribute to
   schools as a learning tool. I always wanted a spectrometer.
   [along with ah oscilliscope] as a kid. I had a microscope but
   found it too "2D" for me.... all that squishing. But the
   interest in learning "what's lies beneath" has always stuck with
   me and kept me learning.
