What are you trying to sync? Would rsync do the trick?
At the very least, a Thunderbird mail profile.
Would rsync do it? Probably.
Got the iBook ("late 2001" model). I do believe I will keep OSX. I've got it just about where I need it to be. Only remaining glitch is syncing the Palm -- it wants to work with a Palm brand USB serial adapter, not my offbrand exact same thing. Got one on order.
Rsync, however, has been a problem. OSX's native rsync keeps glitching on some files when I syncronize my mail (.5GB worth of stuff, going back a good while). Googling on "OSX rsync problem" tells me I'm not the only one with "issues".
The latest rsync, installed using
fink appears to work properly.
