I would actually kind of like a product like this, so I'm not trying to be dismissive, but I have some reservations. It will be interesting to see what kind of range will be actually possible. Has an actual prototype been made? Why use shopify and not Kickstarter or IndieGogo? I'm guessing they were rejected from one of those and decided to forge their own way.

PS - two accounts were made just to comment on this post - sarx88 and kaustubhvk, seem to be sockpuppets.
