I've been using Box.net for a little while now, and while I've had decent success with it (and love the free 50 GB of storage), I've been wondering if there are better alternatives out there. Dropbox and SugarSync seem to be Box's closest competitors and, from what I've seen, have had great reviews. One feature I like(d) about Box.net is the ability to create a Google Doc, but lately, it's been crashing on me (i.e., I can't create/edit the Doc). Do either Dropbox or SugarSync offer such a service (and does it work?)? Are there any other cloud storage options that I might want to look at? As always, thanks in advance.
