When they were trying to do more with Carousel & Mailbox is when things began to feel like they were losing site. But Carousel was really consumer-focused, whereas Paper is clearly (presented as) a business tool. I think that they realized with Carousel that most Pro users use Dropbox for work, so that is where the money is. As someone who also uses Dropbox for work, I think that they could make Dropbox even more attractive by adding some services. They should not try to compete heads-on with full office suite, but I can imagine that Paper + Calendaring + Chat could really be awesome for work.
