Personally I have nothing against the use of 3D renders, but when you see them you know that whatever it is your looking at is a long way away from being a real product.
The fact that the two images are different suggests that your looking at very early prototype renders and the real thing might look different again.
They look very cool either way, but as a 3D artist myself whoever rendered those images should be ashamed. It's very poor quality work. Nothing more than skinned basic shapes.
Still, they do give you some idea of what the final product will look like and I think it will look pretty sweet indeed.
