Slideshow: 10 Great Google Apps Add-Ons for the Enterprise
Cloud Computing Definitions and Solutions

Dashboard requires you to log in even if your browser is already logged into your Google account--a thoughtful security precaution considering how many services are collated here. On my Dashboard, I have an overview of my usage of twelve different Google services, ranging from Gmail to YouTube, with nine more services helpfully collected at the bottom of the page as "not yet available" in Google Dashboard. Seeing how much data you have stashed on Google servers in one go can be somewhat mesmerizing--and if you're so inclined, you might want to go back into moribund services and either clean them out and make them useful. (Somehow, I don't think I'll ever need immediate Web access to my calendar from July 2006.)

I'm a fairly early adopter of most things coming out of Google Labs, so while I don't know that this is a canonical list, here's what I currently see in Dashboard: Account, Alerts, Calendar, Contacts, Docs, Gmail, iGoogle, Reader, Talk, Voice, Web History, and YouTube. (No, I don't have a Wave account yet. Hint, hint.) Services not included: Analytics, AdSense, FeedBurner, Google Base, Google Groups, Maps, News, Page Creator, and Subscribed Links.

Now if you'll excuse me, I have to go look up a few of those and remind myself just what the heck they do.
