Remember The Milk

Task Coach can manage composite tasks, RTM cannot
Until now I used Remember The Milk [4] for tasks used on more than one computer. RTM is able to sync the tasks from the private and the jobs computer about the internet. Since I know Task Coach [1], my new favorite task application is Task Coach, because it can manage hierarchical tasks and can add notes and files to taks and sub-tasks. The synchronizing of tasks is also possible by installing the portable version of task coach in a folder which I sync with Sugar Sync [2] about all my used computers. Each task in Task Coach can be assigned to a category. In difference to RTM all categories can be structured hierarchical as the tasks itself, and it is very comfortable to filter / find tasks by clicking the categories. Since SugarSync has now 5 GB free storage at the beginning and you can sync unlimited devices (instead of max.2 until Oct.2010), it is no longer necessary, that the task-app itself has an online storgage as RTM has, the task-app must only be availbale as a portable app as Task Coach is. SugarSync Registration Link for syncing Task Coach on unlimited devices with 5GB online storage, see [3].

I hate the fact that it doesn't have a decent calendar for task viewing/organizing. Other than that, it's a pretty complex (sometimes too complex) and complete task managing system. Still, this one flaw is preventing me from using it effectively on a daily basis instead of Google Tasks.

Yes, the best online todo list, but do not forget it does not have full backup/restore functionality :(

RTM is the best online ToDo List I know. I like the full access from Google Calendar and from Windows Mobile devices:

The best thing about RTM is the fact that it's everywhere! Access it from their website, your mobile phone, your vista sidebar, igoogle, your gmail account..... the list goes on and on.
