I like that it allows me access from anywhere, even when offline! It's easy for my team members who are not always in front of their computers (or phones) to use as well; they can simply log into our shared workspace with ease.
There aren't many things about this software we dislike at all - maybe some minor features could be added or tweaked here & there? The only thing i'd say isn't great would have to do with how easily one loses track of which files belong where once you've opened more than just your primary documents folder. This has really helped us streamline processes within our organization by allowing everyone to work together seamlessly without having to email back-and-forth over links/attachments etc.
