I pretty much agree. Correct me if I'm wrong but Dropbox were the first to have come up with Camera Upload feature, which basically makes any average user go trouble free with their cellphones, tablets, snapping away photographs knowing that they will be ready on their desktop to view if they want to.

Google+ does that too now, but this is in fact a killer feature which has been adopted well by the average folks out there. So yes, Dropbox is not just about file sharing anymore.
