I was using 30 Boxes and Skobee to keep track of gigs and events, but I can't see any reason not to shift everything across to the newly launched Google Calendar.

All of the functionality I need from Skobee (agenda view) and 30 Boxes (calendar sharing) is present here but with the Gmail UI that we all know and love. Calendar provides integrated notifications and address book functionality from Gmail, lets me log in with the same account, and ultimately looks cleaner than most of the other online calendar apps I've seen. As this is Google, you can easily search your calendar too, and there's the obligatory xml feeds.

It's not all roses though – there are a few bugs (creating additional sub-calendars was a bit flakey for me), and it's lacking a few features I'd like (fuzzy timings for events, like morning, evening etc, some sort of client-side tool so I can sync my phone, and better integration with Gmail; opening a new window isn't terribly slick) – but by and large it's a nice app. One of the nicer things that Google have done is create a set of "remind me" buttons, and accompanying html, which allow one click additions of events into your Google Calendar. This could really catch on – I'd certainly like to be able to add, for example, film timings to my calendar with one click.

Now, would someone please knock together a sync app so I can easily pull the calendar down to Outlook, or my phone!
