Apple has been following a trend for quite some time now where the features I consider "real progress" are barely mentioned, in favor of the more flashy stuff that appeals to the general public.
When Apple developers cater to advanced or "power users" in OS X, it's almost always done silently, or with only a brief mention.
The coolest feature they've added in a while, IMO, is this "hybrid drive" technology - and yet they only mention it because it's a line item that helps them sell higher-end iMac configurations. Fact is though, it's actually a pretty sophisticated advance in OS X itself, the way it plugs into the file system and works at the block level.
So yeah, I'm sure all this stuff like Siri and Maps coming over from iOS will be hyped up -- but long-time computers users like myself won't really care much. I'm more interested in the stuff they do that's buried under the surface. (TRIM support for non-Apple SSDs would be one such thing, but pretty sure they simply leave this off because they'd rather encourage sales of a few more higher-priced Apple replacement drives for out of warranty repairs or upgrades. I've had it for a long time already by simply using the free TRIM Enabler utility.)
