Two things to add: 1. The best use of Tectiles I've seen to date are these on/off switch mats (they're quite cool - but again, limited in who/what they work on). 2. Those NFC 'tap for content' things? I spotted them on SWTrains recently - http://www.flickr.com/photos/whatleydude/8439023580/ THEY'RE COMING.
