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.
