Offline Gmail is being rolled out, allowing you to access your webmail even when you aren't connected. Available in the "next couple of days" to all those who use Gmail in US or UK English, Offline Gmail uses Google's Gears to download a cache of mail for when you can't get online. When there's no connection, Gmail switches to offline mode, which uses local data rather than looking online. For those on flaky connections (on the train, for instance), there's also a hybrid solution.
