Completely agreed. There's no way to make the animation delay be zero, probably because Apple wants you to switch desktops with the motion commands and they want the motion to seem natural, but I have always set them up with <modifier>-1, -2, -3, etc, so I don't think "I want to go right", I think "I want desktop #5". I don't care which direction it's in. Also virtual desktops on OS X are completely broken when you plug multiple monitors in of different sizes. I always end up with hilariously mis-placed, mis-sized windows on both screens. This was how I learned about the "Zoom" item in the "Window" menu: even if you can't find the window decorations for a window (because they're outside the dimensions of your monitor), if you can cmd-tab to it, you can "zoom" it a few times and it will sometimes show up. Also, if you have any "memory pressure" at all, hope you're ready for minutes of beach balls when you plug / unplug the external monitor.
