Agreed. The tablet-like features that got added into the recent versions of OS X are something I don't particularly care for. If I'm on a desktop/laptop, I want a desktop-like experience. If I'm on a mobile device, the paradigm is sufficiently different that it justifies having a different OS.
Good example: the default scroll direction got changed in OS X to operate like a touch device. Hated it with a passion. First thing I changed back.
