Qualcomm, makers of many good things also make Eudora, a commercial e-mail client. However, the e-mail business isn't aligned with its core business of mobile phones, etc. So, Qualcomm has decided to move its platform to a Mozilla Thunderbird base and contribute to that project. Will it actually go somewhere? Its a wait-and-see game at this point.

From their FAQ section:

QUALCOMM has decided not to remain in the email market because it is not in alignment with the core business or strategic goals. By moving Eudora to an open source product, QUALCOMM can exit the Eudora business while still supporting Eudora users and advancing the Eudora e-mail client at a faster pace than before, through the power of the open source development community.”
