I’m looking for a simple task list /todo list for my new N900. Any recommendation?

The contacts program included in the N900 is very poor compared with for example the Palm application. No grouping, no custom fields, no record security etc.. Any recommendations?

The N900 note pad is also very simple. The palm note pad is much better. For example you can switch between notes directly, no opening files as the N900 does. Any suggestion?

The lack on such general features in the N900 gives me the feeling of having bought the wrong device…

Thank you very much.
