Jobs was strongly against the stylus and famously said something like "God gave us 10 styluses at birth". Maybe part of his legacy is a company filled with people having the same opinion.
He has often said that he thought something was stupid. More often than not, at the time he said these things, he was right. He once disliked the entire idea of the tablet, because the technology hadn't matured enough to deliver a positive experience for the customer. Long after he criticized tablets, he introduced the iPad to the world. It doesn't mean he's a hypocrite, it just means that the technology matured enough to change his mind.
Its hard to argue that Wacom technology isn't sufficiently mature, and there is clearly a market for such a thing. Art and note-taking apps are wildly popular. Both would be significantly enhanced by the presence of a true touch-sensitive stylus.
Apple didn't intend for the iPad to be a content creation device, but now they seem to be embracing it as such, because that's what many customers want to do with it.
If a person never changes his mind about anything, that person has stopped learning.
