The VS2010 code editor has been re-written in WPF which enabled Microsoft to put a lot of fabulous features in there. One that I am very fond of is the zoom which you can get by holding down the CTRL key and moving the mouse wheel. At the moment, I love it because it's silly fun. But from a more practical perspective, it will be really helpful when presenting at conferences.

It also highlights one of the values of WPF which is that people who have to work on computers for a living don't tend to have a lot of fun working with their software. With the visual bells and whistles brought to the UI by WPF (and Silverlight for that matter) you can design your software so that it is not just a more pleasant or less arduous experience for the users, but perhaps even make it fun.
