I don't think there's a much space between MacBook and iPhone which allows iPad to exist long, however, if there was, Apple is seemed to have made a great mistake in its implementation.
Does iPad deliver an excellent experience in browsing web pages without Flash?
It didn't matter, indeed, because people doesn't want to see Flash images on web pages inside of the iPhone's small frame. But iPad has the full-size screen to deliver the similar experience to that of PC. People may be disappointed to see many broken pages based on Flash technology.
I agree that HTML5 is the way to go. But it takes another couple of years to replace Flash by finishing up the specification of the protocol. Missing Flash is making iPad's shape blur in the market.
