Dropbox's situation seems extremely precarious. Most users have less than 2 GB of data. That's not lock-in, that's a few minutes of moving. I have about 15.000 high-resolution tagged photos on flickr - that's lock-in. Simplicity and transparency (from where I'm standing) seem like the things that helped Dropbox proliferate - no fuss, just a directory that syncs, but it also means they have no way to monetize their service (they haven't made a dime from me yet) and they provide no added value. Now, consider my case. I don't even have to remove the Dropbox client. The folder is already mirrored on my computer, when I install the next version of Ubuntu I have to explicitly add the PPA and install the proprietary Nautilus extension. If I don't do that, I can just drag the folder to another service. At some point it's easier to quit than to continue using it, which is why I predict Dropbox is fucked once Google provides the same transparent syncing with added value of its services.
