It appears that the only integration with smartthings is through Ifttt, and is pretty limited.
So unless you’re absolutely in love with the form factor, I think most people would go for a regular dashboard with action tiles or sharptools instead. You could present all the same information but in a way which was much easier to read. Plus it would cost less (a lot of people use a fire tablet for the hardware) and you could include camera feeds if you wanted.
So more functionality, more customizable, and less cost. Again, if you happen to be in love with the glance clock, choice is good, but I think most people would just go for a dashboard.
