GMail Tasks

The Toodledo site has a nice features comparison chart that explains typical functionalities offered by these tools. Knowing about these can help you find the best-fit for your needs.

I've been using the Tasks feature within GMail for quite sometime as a seperate account is not required. I only recently noticed that a new GMail Tasks entry can be created for an email by clicking the "More Actions" button in the Inbox header and selecting the "Add to tasks" option for an email that needs to be tracked as a task.
