When it comes to machines, I've been of the belief that functionality is itself a big component of the thing's beauty. If its capabilities are such that make it unparalleled when in action, whether that action be moving through the waves, over the ground or in the air, then it has achieved a level of beauty that the others, while more aesthetically pleasing, never will.
That's just me.
Then again, I like products made of dead pigs.
