Andi let me know that they have just released a free application called Taskify! The application simply lets you save an email as a task. The saved task is then automatically put in your To-Do list.
You can pick up the application OTA at this link or you can read the description and pick up the desktop install at the product page. This latest release was just put out Nov 6th so its brand spanking new.
Thanks to AtomicHelix for another great free app!!!
