No, you're not the only one. I also had wanted Apple to make one too before. It would have been the perfect companion display for the 21.5" and even a more viable option for "Apple-only" Mac mini and Macbook buyers.
But now I'm sort of leaning for them to skip to a 23" display, while also updating the iMac 21.5" to 23" as well. The size disparity between the 21.5" and 27" is sort of huge, don't you think?
This is a common complaint amongst iMac and ACD users. Yea, I really wish I knew why Apple did this. Very ugly indeed, I agree.
This is one of the caveats of the minimalist approach - No ergonomic height adjustment for ACD - You would need to mount on a different vesa Stand or Arm
