In a future perfect world where a % of the urban population is wearing or carrying a device that is capable of augmenting reality what are the surfaces, contexts, textures where we are most likely to see, er, reality augmented? And of course augmented with what?

Given the challenges of smoothing-the-edges between the physical and the digital what are the inherent properties of the urban landscape that make one surface more or less augmentable? Is it the white spaces that are overlaid with informational and advertising hoardings? Or is that blue sky just a bluescreen waiting to happen?
