I think it is a logical demand, but let the Google first focus on compatibilities with their own versions. If they can handle it they can go ahead working on compatibilities with other OSs as well.
I know that these two issues are not connected much with each other, but it requires enormous amount of efforts, to make the devices compatible with other OSs it needs to standardize the hardware, and that I think Google will not be ready to do. Browser is a completely separate case in OSs, and because of its uniqueness they could do it.
I am surprised to know that these are manufacturers. As far as I know that none of these are having their own manufacturing units, they are simply importing their phones from different Chinese original manufacturers. If you see their website you will not find consistencies in their models, every other day they are coming with a new model, very fast as compared to Nexus, iPhones, Moto etc!
Jessica - "I think they'll need to be compatible (or "seamless") with non-Android handsets."
I totally agree. That's one of the nice things about my Google Docs example. It doesn't matter what OS, device, or browser is used. It just works. I also don't have to do anything special to set it up that way.
""We want the experience to be seamless, it shouldn't matter what device you were using before, we want you to be able to pick up where you left off," Pichai said, adding that Google's philosophy puts mobile devices at the center of the user universe."
Google does a nice job with the capability in Google Apps. I can have a Google doc open, at the same time, on my phone, my tablet, my desctop PC, my laptop and my Chromebook. Whatever I type on one immediately shows up on all of the others.
That feature virtually eliminates the concept of needing to sync. It also works when other people are working on the same shared document. I can see the possibility of edit wars between telecommuting co-workers, but I haven't heard of that happening yet.
The article says, "Google partner with three Indian OEMs to create a Smartphone with dual SIM cards, an SD card, 4.5 inch screen, and FM radio for under $100.", but on the contrary there are not even a single OEM in India manufacturing their own mobile handset, then from where Google has found three different OEMs in India?
@Kinnar, the three Indian OEMs are Micromax, Spice and Karbonn.
@joondan : The discussion is not to have a same resolution display in all the devices. The discussion thread is extending on compatibility. This original post was to bring in notice that upgrades without considering previous compatibilities will be increasing e-wastes. No doubt that Google is doing fairly good, and it is the pioneering force in letting virtually every hand a smart OS/Phone.
