"May not be the smartest move"
Sure, Borkzilla screwed the pooch over the Windows Phone, but it's a habit at Redmond to bury projects (usually after a few years of use, though).
India is a different use case. As noted, they are "fiercely patriotic". They're also quite a lot of people. It is possible that a home-grown phone could stand a fighting chance.
I'd rather like to see them try. In the event that it does fail, then we'll truly be able to go back to our newspapers and mutter "well, it's Android and Iphone from now on".
