Sorry but there's a reason why the comments here are negative. I'm a temp designer and even I stay away from transitions, they are almost always inappropriate, slow down the experience, distract attention, delay response. Especially as users get better and more familiar with using the app and use it more and more. These transitions start to become obnoxious.
Just look at the mess caused by CSS3 transitions over the last 4 years. Especially those stupid Parallax backgrounds. No longer can you simply scroll down and have the page and images go up... Oh no, now the images fade in as you scroll down, pop in off screen, backgrounds move at a different rate than the rest of the page. And for what? To impress someone? It's annoying, not impressive.
On the other hand, with the examples Craig Dehner gave in this article, motion design is great for tutorials so you can see what elements changed, where it went, etc... It would be nice for an app to have transitions only for the first 3 times you perform an action, after that they disable.
