Indeed - SyncML is well known and supported within Nokia (both in their smartphones and their simpler series40 phones), and with a simple client can connect to Internet SyncML servers, which can then be synced with other devices and programs, eg Outlook. It also fits into the ethos of the Internet Tablet too, by connecting to an Internet service, not a desktop client.

I notice the Maemo roadmap already has "Tablet/PC/phone sync framework" in the community wishlist.
