No! I didn't say that! Not all appliances are suited to be open sourced
(microwave ovens for one). And you should see Open Sourcing the product as
an *extra* feature of the product, not a product in itself. People won't
just buy a product because it's open-sourced. They'll buy it because they
like the price and the features. The Open design may make them decide to
purchase the product instead of another one which isn't open sourced.

Well, if you're going to sell CE you should purchase at least a 1000 as you
can certainly expect to sell that many, so that shouldn't be a problem.

True but being able to alter and change the firmware will do in most cases.
You'll still need the full design schematics to truly be able to program the
thing, though (unless the code is very well documented).
