Spot on. I am incredibly optimistic about Dropbox's future. It constantly blows my mind that home users don't have any file sharing running on their network. The go-to solution is to email files to each other, even while sitting on the same network. When I learned that Dropbox supported LAN sync, I immediately started recommending it as an alternative to emailing files back and forth. Just drop files you would normal…
If anything, what blows my mind is that Microsoft has failed that significantly on connecting systems which share a LAN. There should have been something as easy as Dropbox built into Windows, and made known to users, at least 10 years ago.
With Windows 7, I need to connect to a network, customise my security settings so that files can be shared, and even then I need to go into advanced permissions and add a user called 'Everyone' to every folder I share, just so that other people can access them. Sharing on Windows in its current format is unaccessible and difficult.
(Maybe I'm doing something wrong, but I'm very computer literate and it's a fight every time I want to share something, so I can't imagine it's easy for 'mum and dad' users)
