Mobility Email, the portable Thunderbird email client that includes Enigmail OpenPGP and the ability to access wemail, now is available with Thunderbird 1.5beta2. This is a significant update of the email client, and offers new features like podcasting while closing security holes. Best of all, Mobility Email is mobile. It can run off a USB drive, and you can take it anywhere with you. This means that your email and contacts are no longer tied to your computer, but can follow you around.
