Apple loves big numbers, and a recent employee meeting had it reveal a pretty big iPhone-related one-- iPhone sales have officially reached the 1 billion milestone.

"iPhone has become one of the most important, world-changing and successful products in history. It's become more than a constant companion. iPhone is truly an essential part of our daily life and enables much of what we do throughout the day," Apple CEO Tim Cook says. “Last week we passed another major milestone when we sold the billionth iPhone. We never set out to make the most, but we’ve always set out to make the best products that make a difference. Thank you to everyone at Apple for helping change the world every day."

The announcement comes 9 years after the revelation of the first iPhone, and almost 5 years the death of the late, great Steve Jobs. It also comes at a perhaps not-so-great time for the smartphone, as fiscal Q3 2016 sees iPhone reach a historic low of 40.4 million, a -15% Y-o-Y decline from the 47.54m sold the previous year.

Microsoft presents what it describes as a more flexible model for the sale of hardware at its Worldwide Partner Conference (WPC)-- Surface-as-a-service.

As the name might suggest, Surface-as-a-service allows partner to lease Surface hardware and associated cloud software on a subscription-based basis. In Europe the scheme sees launch through ALSO, and involves a Surface tablet bundled with Windows 10, Office 356 and other ISV software.

"This will complete your ability to offer services for cloud, Windows 10, Office 365 and for Surface so you can have one end-to-end holistic offering for your customers," Windows and devices boss Yusuf Medhi says.

Accessory maker Incipio buys into audio with headphone vendor Skullcandy, in a deal worth approximately $177 million in cash.

The deal covers the two headphone brands owned by the company, Skullcandy and Astro Gaming.

“We have long admired Skullcandy’s culture of innovation and ability to create pioneering audio experiences with quality and style," Incipio says. "Skullcandy and Astro amplify our dynamic mix of products and brands, while bolstering the technical and operational capabilities that serve as the foundation of our platform. The team at Skullcandy and its international presence will also allow us to accelerate the global impact of our multi-brand offense.”

The Microsoft ownership of Nokia comes to an end-- according to The Verge an internal memo reveals Microsoft is writing off $950 million as part of the failed acquisition before slashing 1850 jobs.

Most of the job cuts (specifically 1350) affect the Microsoft Mobile division in Finland, and the company hopes to finish the culling by end 2016. Microsoft will still keep a small number of ex-Nokia staff, some in R&D roles and others in a Finnish sales subsidiary. Either way, $200m of the $950m impairment charge covers severence payments.

The news comes little more than a week after Microsoft sold off the Nokia feature phone division to HMD and FiH, not to mention Nokia licensing its brand for new mobile phones and tablets. Interestingly, the feature phone business sale announcement included a curious statement claiming Microsoft is not giving up on Windows Mobile-powered smartphones, and will continue supporting such devices and OEM partners.
