G1 Phone and emerging market devices

Why are we interested in a new software for mobile devices?
Mobile phone frameworks are around since the mobile phones are around and now it's more than 25 years. What are we doing so special or wants to do so we need these new generation of software frameworks for all kind of mobile devices.
One interesting fact is that more consumer or may be Telcos want people to use non voice services. Revenue from voice is declining and all of us are finding many different ways to talk (Skype, GTalk etc.) So now you need to push more and more content to consumers handset. But the problem with our mobile phone is that it's a small screen device, memory is limited, processors are slow and last but not least power consumption is important too!
Googles or Microsofts of the world want everyone to use their serivces from their respective phones and mobile phone industry is so fragmented that they can't port it once and get the assurance about their service availability on majority of the devices. What developed contries are using as mobile device and networks, we in the emerging countries are still not thinking about (we may have global launch of very high end handsets from India but still users for these devices are very low). 6 out of 10 new subscribers are going for low cost devices in one of the fastest growing markets like India and believe me most of these consumers are prepaid users, who loves to give missed call if they want to talk to you.

How do the complete ecosytem run on these kind of scenarios?

Someone has to fund for the entire effort, so now atleast for the top 20-25% of the mobile market segment we have Apple, Google, Microsoft, Symbian, who don't want to make money through their software but from the services provided on these devices.

There are many unanswered and comlicated questions about the viability of these option, which are primarily driven by potential Advertising, music download etc. kind of revenue opportunities.
