For me to adopt cloud storage more readily, I would have to see: a) greater demonstration of security of the service, and b) the ability to mount the storage device (NFS-styley) across various platforms.<p>Dropbox's syncing daemon doesn't quite cut it on the elegance factor for me, though it does serve the purpose well.<p>All the same, DropBox is an essential tool for me, and I grabbed my free 5 gigs from Amazon this AM. Can't wait to see in what direction cloud storage providers head as the industry grows.
