Looks like they are just a couple days behind schedule, but PocketMac is set to be released any minute now - it's the first and only way to synch up pocket pc devices (like ipaq) to mac os devices (like ibook). And, if you're looking for synchronistic reverse multiplicity you could get an ipod and synch it up to your windows os device through xpod.
