If Microsoft wanted to convince people that it had any ambitions in the handset world, the news today does a terrible job. The company claims that it will continue to "support" Windows 10 Mobile and devices like the Lumia 950, but makes no mention of building more. There is a line to say that the outfit will "support" partners like Acer, Alcatel, HP, Trinity and VAIO. Otherwise, it looks like Satya Nadella believes that his predecessor's grand push into the smartphone wars was a mistake. After all, the company's most recent round of financials revealed that Lumia sales have fallen through the floor.
