Zero-click search is really impressive when it works [edit: actually, this is zero-search search: you get results without searching, simply based on context]. I think greplin can make it work with heuristics + usage data over the last few years :-) Showing not just what's next, but context (when, where is it? what emails are related?) makes this really cool-- something that can very quickly form a habit, perhaps.
PS: why show Sunrise and Sunset times?(first screenshot on landing screen) Do people actually search for that? Personally, I don't care-- the day starts when I wake up.
