iPad cannot be any of those million things, no more so than a map of Paris is Paris; all it can be is a picture of those things under glass. Pictures of things might be the best we can build today, but it's a limited and unexciting dream for the future.

I don't think you should get points for saying "we should do this impossible thing, that would be better."

When everyone else seems happy to accept that a picture of a piano is a piano, maybe you should get points for pointing out that the Emperor's New Clothes are lacking many important features.
