I have heard great things about Microsoft's Windows Phones and Nokias hardware, but this move is confusing to say the least and I am not quite sure why it is necessary. MS designed the WP OS to run on moderately speced hardware but not on low-end devices? And now that they want a smartphone for the rising markets, they go looking for suitable software, which they find in the lap of their immediate competitor?
