>On the other hand, I can't think of a single new feature they've introduced since 2011 that matters.

Honestly that's what I love about it. I work on something on my desktop. Then when I go to my laptop, everything is there too. It's great. When I get another computer I can just enable Dropbox, walk away, and all my projects, notes, pictures, etc. will be there. I pay them some amount of money per month and it just works and I very rarely need to visit the website or even click on the icon in my toolbar.

Sometimes I read notes on my phone and it's kind of annoying that I can't search through text using their app, but I generally consider that to be a problem with Android rather than Dropbox.

I generally have not thought about how Dropbox spent its money until I visited the web interface, which has been redesigned for the tenth time over, and remembered that there’s still no way to see how much space your folders are taking up.
