I am currently involved in the final stages of visual radio testing here in Singapore.
We are using the prototype Nokia 7700's (stormtrooper machines - no wonder they never went to market!)
My assessment: Very little future here. It's neat that our radio stations can beam info, but WiMax will superceed this VERY quickly. It's WAP all over again...
Forget this stuff... NEOM's bag is where it's at...
