Being so enamoured with Gmail, I have started using it as my primary email address. But Gmail is still in beta; what if Google simply decide to drop the whole idea?

I have come up with a workaround that minimises the impact of such a thing happening (unlikely though it might be):

1. Auto-forward the emails to your regular (ISP) account to your Gmail account.
2. Set the 'Reply-To' address of your Gmail account to that of your ISP account.

One drawback is that you would have proudly given your Gmail address to impress people, and if they type this address manually rather than replying to your email to them, you'll be back to square one. But considering that people prefer to reply to an earlier email even if they want to start a fresh conversation, this is not a major issue.
