Font picker is a simple application for graphic designers. It lets you browse the installed fonts on your computer and then narrow down that selection till you find the perfect font for your design project.
The days of squinting at small font samples are over. Once you've got your short list of fonts, you can save it or share it using the share charm.
UPDATE 5 December 2012: Just sent version 1.2 to the store. This version includes search.
