At Wednesday's media event announcing the iPad HD and the new Apple TV, Apple CEO Tim Cook touted the "post-PC" era. He says that Apple's line of iDevices (iPods, iPhones and iPads) has sold 172 million units and now comprise 76% of its total revenue.

But don't take that as a death knell for the Mac. The computer still accounts for 24% of the revenue -- and 24% of Apple's income is a LOT of moolah.

That said, expect to see the Mac get more iDevice-ish in the months ahead. Apple doubtless plans to lure all those iPhone/iPad lovers to the company's computer platform.
