My treo 650 is on its way. I want to organize my tasks/to do etc. and I will be researching the best software to purchase. I assume these apps have a laptop version as well so I can sync up. I have web based e-mail which is IMAP, it has a calender but does not have a way to track tasks. I plan to purchase chattermail as an interface to my IMAP account since I want an instant update when I receive e-mail. Then I would manage my tasks and to using the software on my laptop and treo. Is this possible?

I hope I am clear.
