I'm either a fortune teller or it was completely obvious that Dropbox has been meandering for the past two years. Today they announced an end to both Carousel and Mailbox. I never understood how Mailbox sold more Dropbox subscriptions. Carousel made more sense but I never got behind Dropbox as my photo service because it was just too expensive for what the value it provided to me. What a bummer for users of those products.
These experiments are why I continue to be nervous about Dropbox as the only viable syncing solution on iOS. If that goes, we all down with it.
