Well, I've done much the same, and that's the thing:  are we building a
mainstream product with current technology, or something intended for our
personal nostalgia and historical re-enactment?  Either can and maybe
should exist.  They're not the same markets.

Townsends sells slates and slate-pencils, so maybe I can't say those
products are "gone" either; but they don't meaningfully compete with the
Apple iPad.
