Not really, as they have no story for Mono not to mention ARM NEON support.
Complaining about "hip substitute buzzwords" is very hip, though. Thumbs up.
That's one use, but the use of "story" upthread is a different common sense that is actually more like "solution" (and much more of a marketing term) than the requirements sense of "story" used in some development methodologies.
b) Why would Microsoft have a story for Mono? Mono isn't a Microsoft thing.
