Maybe I'm not as interested in this after reading the review, but it's still worth a go. The task management options seem like a good way to plan your day.
I think people who are doing nothing right now, or have their own ad-hoc organization scheme using email will love Inbox. People who have a more disciplined system for calendar/todos/emails will not want to use the reminder/pinning features. But I still found it nicer than traditional Gmail for quick triaging.
