Yea, at this point it looks like Apple is going to just let OS X fade away and push people towards iOS (the bigger pie-slice, you know, for the bean-counters). I think Apple lost most of the hard-core devs who worked on all that cool audio and graphics core stuff that once made OS X so great for the pros. And, then I won't even get into all the amateur-hour remakes of the apps and stuff.
That said, the grass on the other side of the fence isn't that green either (but at least improving), so at this point, I guess the Mac still makes the most sense. As far as graphics tech, I've been a fan of OpenGL for a long time, so I guess that's the standard, despite M$ attempt to break that. I'm kind of hoping the new Microsoft quits trying to ruin the industry and joins in with the standards a bit more, like they've started doing in the browser realm.
