connecting an ipaq with linux is doable, but a bit of a pain. check out http://synce.sourceforge.net/synce/index.php
to start. this will get you connected, and allow you to share files, etc. intall becoming much easier as the project has moved along. there are programs to install files, which i haven't mucked around with. the multisync program/plugin will allow you to sync with evolution; had it working on my previous setup, but haven't figured it out with latest mandriva (nee' mandrake) release.
