Huh. I find that shortcut consistency is actually a strength of the platform. Are you talking about inconsistencies between OS X's choice and the other OSes you use? Because otherwise, I don't see it. Only on the Mac do I know that I can use the same key combo (apple-,) to get to the preferences of an application, regardless of where it came from. And I'm not sure how apple-` is "more annoying" than alt-tab; apple-tab still exists for switching between applications. apple-` just switches between the windows of an application. I actually like that ability, and again, it's consistent across applications.

OS X may not be your cup of tea, and that's just fine. You just happened to attack what I perceive as one of its strengths, so I'm surprised by your choice of targets.
