I'm a linux user so I also run the GPE applications on my desktop. I can transfer the raw sqlite data bases for these applications between the N810 and my Ubuntu desktop. Not quite syncing at a transaction level but works for me. In my case the N810 is my primary PIM data entry device which makes sync by file transfer a viable option. I also use Google Calendar and erminig on the N810 does the syncing on a transaction level with Google.
