I disagree that OK/cancel are backwards. Placing OK on the left makes it a more deliberate choice. Thus the system can be more confident the user consciously chose OK, as it takes a smidge more effort to get there. OK/Cancel dialogs are (unfortunately) very common, it's very easy for users to become numb to them and just click whatever it takes for them to go away.
For similar reasons, Mac OS Classic placed the trash can in the lower right corner of the screen. If you had dragged something that far, there was nothing else you could possibly be shooting for. Therefore making the system more confident you were actually dragging that file to the trash. Which is one reason MacOS never asked "are you sure you want to delete that?" like Windows's recycle bin does by default.
Another similar example: MacOS classic placed the close button of Windows on the opposite side, on its own. Again, if you are clicking there, the system is more confident that closing the window is what you're really after. It's interesting to note that OSX did away with many of these well thought out devices.
I don't understand why putting "OK" first makes it a more deliberate choice. Why does it take more effort to get there? If a numb user's objective is to make it go away as quickly as possible they will become trained to where the "OK" button is and click it without reading anything else.
