The scary part though, is that one recurrent theme I see in nearly every single “how I write on the iPad” story is Dropbox. It’s the linchpin in the workflow. Scary, because Dropbox is outside Apple’s control. Scary, because if not for Dropbox, many of these people would be using their iPads as much as they are. Scary, because Apple’s iCloud falls short of Dropbox.
As one of those who wrote a book on my iPad… Yep. That’s my experience as well.
