I think that abandoning Windows Phone was a bad idea, considering the volatility of the market, growth in developing countries, and especially considering that phones are consumer items which may have a life of only a few years. The well-known alternatives are the overpriced Apple iPhone line and the irritatingly omnipresent Andrrhoid.

As for Gurgle, with their data practices I can't see that it would long before they are embroiled in a nasty Fakebook-like scandal. An opportunity to resurrect Windows Phone is probably just around the corner.
