I use ntfs-3g, it sucks. I can copy files, but cannot delete, or move.
Linux binary compatibility does not work for dropbox. I think Linux uses something called inotify, which the BSDs do not have.
Dropbox requires installing wine. Accessing NTFS requires installing special utilities, and even then does not work correctly. Auto-mounting requires special setup. Getting my privateinternetaccess VPN to work is such an ordeal that I gave up on it. Also, the Chrome browser does not work well, sites crash all time: Aw Snap, Aw Snap, Aw Snap.
I cannot help but wonder if desktop BSD is not trouble than it's worth.
