> Unless someone for some reason comes up with a product that's just amazing compared to its competition but has no syncing capabilities, or syncing becomes incredibly difficult to implement well, I don't see why people would use Dropbox.

For me Dropbox has the following advantages:

* it works with _all_ my files and applications (not only those with sync built-in) * it's a separate product, that does one thing only, where I explicitly pay for that thing. It's not an after-thought or something whose business model is unclear or is against my privacy * for the same reason I am less worried that the company behind it will pull the plug because it's not the main focus

I much happier to pay more for a service/product with a clear focus made by a company that doesn't a gazillion other things. (Btw for similar reasons I think that Evernote is damaging itself with their strategy of chasing new features at all costs).
