Ever since upgrading to Snow Leopard and using Apple Mail, I have been getting the following error after a day or so of use: "Account exceeded bandwidth limits." Eventually I am able to access GMail via IMAP with Apple Mail, but only for about a day before this error occurs again. This doesn't affect my access to GMail via the web interface. Nothing has changed with my use of GMail since before the Snow Leopard upgrade and I've seen scattered reports of this on the 'net, but nothing that nails down a solid connection between the Snow Leopard upgrade and this error.
