Open Sans is a font that stole my heart and my designs this year. It’s by far one of the most beautiful typefaces I’ve ever seen. And it’s perfectly crafted for both web and mobile. It really shines in the latter. The best part? It’s completely free and a part of google web fonts.
If you haven’t heard about it yet, download it:

This font has the best chance to finally kill off the much overused helvetica (jk;))
