I know Evolution is a bit beefy for the Zaurus (SLC-750), but I already use it on the desktop and with MultiSync the syncing would be awesome. I have tried KO/PI but while the Zaurus part is nice, getting a desktop version up and running is painful. I have not tried to sync between them yet because my wifi card died just after getting KO/PI installed on my Zaurus. I use RHFC2 at work and debian Sarge at home, and Evolution is readily available for both, but KO/PI is not. However, the KO/PI documentation for getting it running on the desktop is awful, so I could very well be missing something.
Well anyway, if anybody comes up with and Evlolution IPK I would be happy to be a tester. I don't need any funky plugins or anything.
