What use is OCR on your phone? Seems like a feature you use once to say "oh, that's neat" and then never use again because it's not actually useful, just neat.

With the opening up of the analog TV spectrum, it's likely the US market will get a drastic overhaul too. The FCC wants to do something similar to Hong Kong i hear.
