I’m using a 2017 iMac 21.5″ screen iMac at home. I’m very happy with it. But I must admit that this design is getting a bit old. And one thing that I would like to see in the next revision of this design is the bezels to go thinner. Something along those lines.
This mockup is from Lorenzo Mariotti on Behance network. I rarely like what people are posting as mockups of future Apple products. But this one is very well done. Something that I’d like to own myself.
