Georgia Pro and Verdana Pro
Webtype has released today much better versions of popular typefaces Georgia and Verdana. Not only were they refined, the foundry created all-new styles and weights, all-caps and alternative numerals.
You have necessarily seen and read articles written with either of those, and although they looked great on screen, they performed generally worse on print. These Pro fonts will now look great on both.
