Excuse me, but if there is a "weird ass intentionally hobbled UI" then that's the windows UI. ms was never able to create a proper DE.
Now try switching to that window with they keyboard in OS X, without using any 3rd party helpers like HyperSwitch.
You can't do it.
Also try running 2 instances of the same app in OS X. You also can't do that.
OS X is garbage compared to Windows.
