Many like the design, as it works with any colour of Mac (silver, grey, or any other that may come in future). It's also significantly lighter in weight due to being made of plastic (my metal-framed ACD weighs a ton) so can be moved around without breaking your arm. And importantly it can be very easily VESA mounted (any following Apple's current design, would have been difficult or impossible to do that easily).
As said before, it's design is what used to termed in design circles as "monolithic": strong, sturdy, simple, non-fussy or flowery.
