Yes, sounds counter-intuitive, but the OSes (the platforms) are used extensively on things that are quite a bit like phones but aren't exactly phones. They're used so much so, that they change the market share picture.

They run all the same software. For 99% of programs, if they work on the phones, they'll work on the non-phone items (however sometimes less well). This goes for android as well as iOS as well as blackberry

His sentence makes perfect sense. You just need to level up and put some points into reading comprehension. Go talk to the dudes with the giant yellow exclamation marks over their heads. That will help.

Additionally - meditate on the following koan: if a vendor builds a platform, and nobody builds a device for it, will it still be hyped by the tech-press?
