Dropbox is the shit. I have all my programs for my grad-research in it. I sit at school on my linux box and work. Then I come home and open the same file and work. Then I go to school and work. I NEVER spend a moment thinking about the file or syncing or emailing myself something. Its made my life quantifiably better. Kudos to the dropbox dudes.
Yup - and it's definitely in the "it just works" category.
The folder sharing is also extremely useful.
The only they add the ability to supply your own encryption key (and per shared folder maybe). That would increase it's utility for business. I'd certainly pay a premium for something like that.
Dropbox saved my ass when my computer completely fried (I tried installing Windows on Boot Camp using a Dell install disc and my computer just refused to turn on). About 6 years' worth of essay drafts, stories, and poetry all got saved and backed up instantly - despite the fact that I'd deleted those stories from Dropbox months ago! I'd moved them to my computer from Dropbox and deleted them, but it saved it in my history.
It's not one of my most-used sites, since I rarely have need for it, but I wish I needed it more, because every time I use it I'm blown away by how easy it makes things.
Agreeing it works great. But if you're relying on it for keeping your files safe forever, watch out for the free account policy:
"Dropbox reserves the right to terminate Free Accounts at any time, with or without notice. Without limiting the generality of the foregoing, if a Free Account is inactive for ninety (90) days, then Dropbox may delete any or all of Your Files without providing additional notice."
And I can't find the actual pricing for non-free accounts anywhere on the site, which isn't increasing my trust level.
They definitely need to launch the paid version, but I wouldn't worry too much about your files getting lost. Pretty much by definition you should always have at least one backup of your files. Worst case and they close tomorrow, you still have all your stuff.
Update: They already have paid plans, $99/year for 50GB.
Agreeing that Dropbox rocks. I use it to share PDF's between computers so I can read them easily anywhere. I have code in there that I need between PC's that isn't on some kind of revision control yet, and finally, I backup my all my code using rdiff-backup which just crons it to my Dropbox every few days.
Access to all your files, one-click view for any items MobileSafari can access (doc, pdf, xls, html, etc), and the changes feed for quick access to your most recently used files.
