The categories are still quite confusing, because Apple's products stubbornly fail to fit cleanly in any of the old ones. Is the iPod Touch a phone? No. Is it more-or-less like an iPhone? More, rather than less. Is the iPad a PC? No. Does it replace a PC? Yes and no. Does it replace an iPhone? No and yes. It's reminiscent of the elder days when "microcomputers" were new, and one could have an extensive debate over whether a microcomputer was a real computer or just a toy. In the long run, of course, the very word microcomputer died out.
