No it isn't. Neither market has been overtaken by commodity products at all. Your argument about Apple products being commoditized is totally without merit. The Mac and iPhone continue to gain share in markets that have commodity alternatives. The iPad sales have slowed but they haven't slowed as much as the commodity alternatives. iPod sales have slowed not because people are buying commodity MP3 players instead, but because people are no longer buying standalone MP3 players.
