The design looks cool. Also it will drive itself. Load/unload cargo by itself. The most important thing with a truck is the towing capability and the box space. I would not be surprised if Elon wants to enter yacht building business. The technology to build a boat is much less demanding than to build a car/truck.
Design is damn cool, like straight out of FFVII but yeah as others have said u can't use it as a ute. But then again nobody actually uses their shiny new pickup truck for anything that might incur a scratch.
