Anjal would be wonderful.
That is only if the calendar gets included.

A port of Evolution in Anjal form (or any other form) would justify switching from WinMo to Maemo.

A port of Korganizer/Kmail would also justify ditching WinMo but i'd much rather Evolution(far better calendar sorting/filtering).
