I’ve been arguing for years that the iPad could never replace the PC until it provided all of the features that PC users demand. Well, Apple finally listened. So it’s time to dust off what I’ve been saying for years and wonder anew what took them so long.

“The ‘post-PC’ world that Steve Jobs imagined is closer than many expect,” I wrote almost four years ago while evaluating the then-new iPad Pro. “All it needs is for the major mobile platform makers to subtly shift their offerings to meet the needs to more sophisticated productivity scenarios.”
