With all the buzz about Google Calendar, I skipped my coffee break to give it a spin not expecting to find it very useful given that I rely heavily on my Outlook calendar in conjunction with the rest of Outlook. Still, my only out-of-office access to my Outlook Calendar is through my PDA. I don't yet know if Google Calendar will sync with my PDA.
What particularly appeals to me about Google Calendar even without testing it is the ability to share calendars in a collaborative way. Very 2.0.
I found Matt Cutts review of Google Calendar very helpful and I look forward to digging a little deeper into this new tool.
The built-in keyboard shortcuts look to be handy.
