/me Another raised hand.

Like Matt, I use it for "I need it right now" ad hoc information. Specifically I use the Thesaurus, Converter, Translator, Calculator and 4 world clocks: 3 for clients, 1 set to Cupertino. Doesn't *every* Machead have one of those?

Furthermore, I have the developer mode enabled so that I can "hold" the calculator while coming out of Dashboard and have it over the top of my regular work windows, usually when I'm working out some pixel dimensions in Photoshop.
