There is a video floating around of a Nokia N900 smartphone running the full desktop Mac OS X 10.3. From the author, Tomi Nikkanen: 'I believe this makes the N900 the first smartphone ever to run a full version of Mac OS X (at any speed, slow or otherwise). As you can see from the heavily edited video, it took almost 2 hours to reach the "About my Mac..." window. Keep your eye on the time display as that will give you an impression of just how uselessly slow it is.
