If they can improve the accuracy it will be useful for architects, handy people and people buying new furniture... which means there will be people using it everyday... meters/rulers are done. Great idea.

The pro version must be very nice. I hit the room limit before I finished scanning half my house in the demo version.

Gizmodo says this uses GPS but there's no way that's accurate enough, is there?

Article says it is accurate within 1 foot, which really isn't accurate enough if you are generating floor plans for rooms.
