It's better than existing technologies in the sense that you can put it on a vastly wider array of surfaces. This looks like a very early iteration; I expect the technique could be improved upon to yield higher accuracy and support for multiple touches. More electrodes, smarter electrode coordination, better conductor regularity, etc. could probably all help. Even without these things, it already seems quite useful.
