The promise of locative media seems to remain just that: a promise

Read in the "Rise and Fall of New Media" by Lauren Cornell and Kazys Varnelis:
Locative media remained the stuff of demos and art-technology festivals until 2008 when Apple released the GPS-enabled iPhone 3G. Paradoxically, the mass realization of locative media seems to have taken the wind out of its sails as an art form. Although courses on writing apps proliferate in art and architecture programmes, the promise of locative media seems to remain just that: a promise, its transformational ambitions forever enshrined in William Gibson’s Spook Country (2007), a novel which, tellingly, was set not in the future but in the recent past.

Why do I blog this? The quote echoes with my feeling and it's the second time this week that I encounter such comment about locative media. I actually don't know what it means about the use of this technology but I guess we'll see pretty soon how users repurpose such devices and services to their own context and interests.
