Well, if you don't believe that typography (i.e. fonts) really matters in design, then take a look at this online quiz.Can you guess these movies from a single letter from their poster? You'll be surprised how many that you can guess. Spotted originally on the firewire.
And while we are on the subject of design, I came across this presentation from Will Tschumy at the User Experience team at Microsoft the other day. I really thought this was a useful presentation - nice style too! You will find it here: http://www.slideshare.net/wctschumy/why-design-matters
