Just one more problem: as more and more great platforms become available, there seems to be a trend of users storing different kinds of data in their own specialist platforms. Photos on FlickR, music on Spotify, movies on Netflix, simple documents in Google Docs, code on Github, books on Amazon, mail in Gmail, etc. That leaves less and less stuff for Dropbox. In particular, it leaves less gigabytes for Dropbox, because the big stuff is taken care of. So with the price of storage and bandwidth dropping exponentially and the amount of "other" data dropping, it's going to be hard to sustain a freemium model just based on a storage cap.
