But it's exactly the thing that makes software "delightful". It's also a huge boost to the developer's appreciation, motivation, productivity, care for the product.
But yeah, if you only care about checking the feature boxes.. Go ahead, make shit software with miserable people, but be sure to prepare to go out of business.
The point is a real skybox is not great for satnav software. It's probably actually worse than a stylised mode, with a predictable colour background for anything that's going to sit on top of it.
