It’s fantastic. My most anticipated Google service, I talked about this thing for ever and now that it’t been here for awhile it’s proved itself as the best online Calendar out right now and even Backpacks upcoming calendar isn’t that impressive. Only if it wasn’t one way, meaning I’d love to have the ability to edit my calendars in iCal instead of just subscribing to them, something else it doesn’t have is subscribing to protected webcals.
