As far as web-based calendar services go, Google Calendar is pretty slick. You can even subscribe to iCal published calendars. I personally use this feature heavily to put a prettier face upon my own calendars when I’m on the go and the Palm isn’t around. If I could get Palm syncing and felt comfortable with requiring net access (which I don’t), then I might even consider switching to it.
Its achilles heal was the lack of Safari support. Sure, I could fire up Camino or Firefox, but I really despise switching browsers for different web pages. And I like Safari. That’s no longer an issue. Go ahead and try it out. Good karma to Google for not resting on its laurels.
There was no healing Achilles "heel".
