iPad post-PC future

Found an critical point of view regarding the new released iPad on TechCrunch http://techcrunch.com/2012/03/08/yesterdays-ipad-event-was-only-half-the-story/

Yes, it's right apple stepped with the iPad in to the post-PC future. But in fact this currently affects only the private sector what about the business customers, are there / will there be any business customer stories where the usage of the iPad could replace the classic Personal Computer? What do you think?

Cheers,
