Cutefish is very rough. I do like the look and feel, but I didn't like having what felt like a tablet OS on my desktop.
I will give it some more time to develop though. I love the direction they are going in.
What do you mean by rough? Not as smooth and responsive as say iPhone or iPad or Macbook?
I think it’s responsive enough, it just doesn’t do very much... e.g. app launcher is just a full-screen grid of icons in seemingly random order. At least being able to sort by name or something would be better.
