I'm contemplating buying a G1 and I've been doing a bit of research into the calendar and gmail apps for android, but I've yet to find an answer to a question I have about the apps. Like the web versions, are these applications "online-only"? Meaning, each time I load the calendar app does it go out to google's servers and retrieve all my entries, or does it actually sync and store the data locally? If I'm somewhere without cell coverage, can I still use my calendar app, add entires and have them synced up later when I return to civilization?

Well, to answer my own question (I couldn't resist and got a G1 =) the apps work offline quite nicely. Calendar doesn't seem to flinch at all. You can add new events and view any that were already there. Both the email apps also work offline to some degree. My inbox popped right up, showing all the emails it already knew about. I could even click on and view emails that I had already read, but unread emails would not come up. I was also able to compose messages in both email apps and have them automatically sent out when service was re-established. Overall I'm quite pleased!
