But the biggest thing annex-assistant adds is the automation of syncing; syncing is already builtin to git.
Edit: sorry for being so tendentious (yes, I like big words :). I'm just really having a hard time "getting" Dropbox as it seems like a poor, closed source replacement for rsync. Git can be used as a glorified rsync that will resolve 90% of multiply edited files, plus it gives you change history, and you're not locked into one company. I understand that git doesn't run on the iPad, but that sounds like a problem with the iPad, not git ;) Git runs fine on not just my Android devices, but my Maemo devices as well.
