I'm not so sure about the business model for this. I personally wouldn't watch television channels on my mobile phone. This might be due to the fact that I live in north america where mobile phones seem to be generations behind their cousins in europe. Regardless, I still don't think I'd have the desire to watch continuous television on my phone. However, I would watch 'snippets' of television. For example, I'd watch news briefs, sports highlights, breaking news, etc. This type of service wouldn't require the type of hardware of a fully TV capable phone (I have a feeling these phones are using a form of software defined radio to demodulate digital TV broadcasts...and if they're aren't, they should be). In fact, the 2.5G and upcoming 3G phones could do this easily.
I find SDR's to be pretty cool too. However, I think they can probably disrupt the network side much more than the client side, as they can used to massively consolidate the radio infrastrucure across industries as diverse as broadcasting, data networking and mobile telephony. Why should we have different cell sites, wireless PoPs, radio and TV towers? They could all be replaced by massive compute farms running SDRs.
I agree completely. I think in addition to this, they will have significant applications on the client side. If you can get rid of all that clunky hardware and replace it with some code, the possibilites seem endless. Is there a law similar to Moore's law for the potential rate of development for software applications? If there isn't, I'm calling it Davachi's law. ;)
