Sketch literally gave me the push I needed to go from a non-designing developer to a halfway decent designer. It's really that good.
The major negative right now is performance. I used Sketch to design a full iOS app with 7 or 8 screens on a fast mbp and things were seriously crawling. I had to break up separate screens into separate sketch files and even then it was laggy.
Sketch team, your product is amazing, but performance is a big issue. It should imho be your top priority.
Agreed. Seriously picking up UI design in a post-Sketch world is basically the same as picking up web programming in a post-J2EE world. You dodged a bullet.
(I am pretty proficient in Photoshop, but never had to design a photorealistic mobile UI in it. What a nightmare.)
Agree with your initial point. It's quite easy and intuitive for us non-designers too. Been using it past couple of months and prototyping my apps here.
