I started an account, but felt it wasn't very compelling to actually get started using it. I've synchronized my email and calendar, but it isn't jumping out at me how this will be superior to my current workflow (I use Things and Calendar on MacOS/iOS, and they integrate very dumbly but well enough). At the risk of sounding dumb, what is this supposed to offer that my workflow doesn't have? I see it can support contacts and files as well, but I'm not sure if/why I'd need that. I have all of that on MacOS/iOS already, so when I add contacts or references to files it'll come from iCloud or whatever. That's fine for me. Is this for people with more disparate and less integrated systems? Am I missing out on something? The main appeal to me is having task lists working more like documents; Things doesn't support this and it's fairly inflexible in that regard. I do wish I could plan projects and take notes a little more freely in there. But I'd also worry that having this freedom might be a distraction, too.
