Well, that's what I am planning to do anyway, but I want to know how large these automatic transfers needs to be :B

Actually I have had easydeb installed a week or so, tried it first time yesterday. I don't think there were too many simple freeware planning applications on windows, I don't know what exists on Debian. My needs aren't too different from what I'd want in a simple calendar like the one already in the N900. Just bills instead of tasks. Also, the N900 one doesn't work too good on recursive things anyway. But it works better on set dates than every 2nd monday, so I guess it'd do.
