To the list of failed Apple products add the Newton/Message Pad and the pre-OS X OS which never materialized but took years to develop then got dropped. The dumbest thing they did was to pull the hardware licensing away from other manufacturers in the 1990s. When Jobs returned, so did greed. Most of the third party hardware companies were turning out cheaper and much better MACs than Apple was! Had they backed away from hardware domination and focused on software they would have a much larger share of the market now. Eventually the iPhone will no longer be the cutting edge smartphone many still believe it is, and iPhone sales will plummet and one of their cash cows will go away.

To the list of Sony standards and products that failed add Betavision, the Clie line of PDAs, and whatever proprietary format they used with their clamshell Bookman. The clamshell Bookman of the mid-1990s used a minidisc, but Sony never provided more than a handful of books for the device.
