A couple of quotes from this which I loved...

One of the best ways to make a product enjoyable and easy to use is with an interface that is simple+clean. Give the user what they want, the bare essentials, and make the information easy to digest. It's not about being the prettiest either.
Don't be afraid to call out your competitor and wage war. You should be respectful of course, but it's okay to stir the pot.
