Is this true? Seems like a huge oversight - why would you implement syncing without deltas?
Yeah, unfortunately they do not offer uploading just the changes.
It is geared towards documents, rather than large files.
Documents benefit enormously from delta-sync.
No wireless. Less space than a nomad. Lame.
The difference of course being that Dropbox has a significantly better user experience than GDrive, while the Nomad was a significantly worse one than the iPod.
