Two things.
Why would Apple kill very close to half of their revenue and most recognizable product? Unless there is a bunch of real maniacs in the place, they would not do that. The MacBook Pro was never Apple's main product, by then the iPod was dominant, and the iPhone was a year away.
Second, Apple was great in the 90s? They almost shut down because their product line was so complicated and stagnant, very few remember those as the good days. Apple now is no different if not better than it was in the 90s.
