The Biston theme has a cool wheel-style dock with 9 user defined icons on the homescreen, nice big battery and signal meters and a Today preview for your calendar and messages. Fonts are customizable as well, and you can even change the menu font. This theme also includes what Hedone calls DFK (Double Function Keyboard), which is basically a set of custom shortcut keys which are good to get familiar with. More information on DFK available from their site.
