On this "Apple should buy / copy Dropbox" thing...

Dropbox is wonderful. I love it. But Apple is slowly moving away from exposing the filesystem to the user, so if they do anything, I don't think it'll look or work like Dropbox. For example, Dropbox's solution to syncing conflicting versions is to let you browse revisions on the website. I don't see Apple doing it that way.

I would foresee an SDK level feature with each app responsible for integrating and syncing its own data. This is possible now, if the app maker is willing to host a server but the overheads of running a server long term discourage it.

Who really thinks Apple is going to build it and give it away though? Sure, there'll be efficiencies in terms of code reuse and scale if Apple provide it, but it'll cost the developer somehow (and there'll probably be another storm in a teacup when they announce it. but that's another day's work.)
