Mac OS X "Has Mountain Lion been feeling faster for you compared to Lion on the same machine? It's probably not just you: Mountain Lion appears to include improved graphics drivers and low-level graphics subsystem improvements. According to our testing, these improvements result in an approximate performance increase of up to 10 percent. Those improvements can make your current hardware feel faster despite the fact that your CPU can't magically crunch numbers any faster. The changes also lay the foundation for Apple to update OS X's OpenGL support in a more timely manner, which could potentially lead to better graphics performance in the future."

OK, I love developments like this... Performance at both high end and low end (integrated) are awesome.
Changes like this, as well as other performance related subsystems, and subsystems which may enable new development approachs, etc. are exactly what I look forward to in an OS release. All the iPod-ization UI stuff and changes which are basically APPLICATION updates (not OS updates) are really rather low on my list, even if might applaud a minority of the changes Apple is doing in that department.

I get it that this stuff may not be 'front page' material in terms of their core marketing audience at this point (remember when it was?), but why the need for secrecy, why not have a detailed description of technical sub-system changes available for those interested in it? Not to mention developers who may be dependent on things like the OpenGL stack.

iOS or MacOS X developer? WWDC videos are there to detail such changes ;) .

I had a look at the videos and they really don't go into much details other than "this is what is new and this how you use it" but nothing mentioned on how Apple actually has improved the underlying performance such as "we're now using Core Animation in more areas, we've migrated the Core technologies from OpenGL 2.1 to OpenGL 3.2" etc. This is the one thing I love about Microsoft - when they changed GDI in Windows 7 they not only said, "this is what we've done" but actually explained how they went about it, the design limitations before and how they were addressed. For me I think that if Apple spent the sort of time Microsoft does they would earn a decent amount of geek credibility as a company that makes great products but there are some real technical underpinnings.

Now that Apple have publicly committed to a more or less annual upgrade cycle for both OSX and iOS I wonder how that will work out.

I presume with iOS at V6 and OSX at version 8 (since the first release) a lot of the heavy lifting that must happen in the first few years has been done and the engineering team are less stretched and can concentrate on polishing. If there are major structural changes to come I would expect them more on the iOS side.
