So what is the Pro part?
After reading article and all comments, still struggling to figure out what makes this more suitable for "business" than a regular iPad? I assume they are talking about the few who use Mac's for business, which is still mostly in the content creation realm. Until Mac's and iPads can play with enterprise stuff like Active Directory and actually run software used in business, the world still belongs to Windows/Linux.
This just seems like an attempt to combat MS Surface Pro commercials. The difference is those things can act like Win desktop/laptop, join AD domains, and yet still be a tablet my pre teen can play games on. Will be interesting if this goes anywhere.
