I think two paths lead from here: Apple continues with the Mac as workhorse OS, and the iPhone OS as the mobile entertainment focused interface (as the iPad currently is), or, like MinimalMac states, the MacOS ends here with mouse and keyboard, and they will slowly turn to touch interfaces.
In either case, the iPad continues to be a home entertainment device, and in no way a netbook or tablet competitor
