Let's talk about the Sony Xperia Z4. The Japanese electronics giant announced the latest in its line of premium Z-series smartphones recently for its home market. And it's fair to say the popular reaction to the device has fallen somewhere between bewilderment and outright derision. Consumers and critics alike seem confused as to why this phone exists, questioning the priorities Sony's taken with what appears to be its early-2015 flagship.

With questionable hardware priorities and no word of any global launch, it's a bizarre turn for Sony, coming as the company looks to restructure and streamline its smartphone offerings and focus primarily on the high end of the market. The Xperia Z4 can boast only a couple of meaningful improvements over its six-month-old predecessor, and in one or two important areas it may actually be a regression from the Z3.

When Microsoft releases Windows 10 later this year, it will come with a new design language which has slowly been uncovered with the latest builds of Windows 10 for phones. One member of the Windows community has put together a massive guide that shows the transitions from Windows 8 and Windows Phone 8.1 to both Windows 10 and Windows 10 for phones.

I missed this when reports first came out last week: with iOS 8.3, file managers such as iMazing and iExplorer can no longer access the document libraries of iOS apps over a USB connection.

Microsoft's launch of Windows 10 will likely take place in late July, according to AMD. During AMD's latest earnings call last week, president and CEO Lisa Su revealed the launch timing for Microsoft’s Windows 10 operating system. Answering a question on inventory plans, Su said, "With the Windows 10 launch at the end of July, we are watching sort of the impact of that on the back-to-school season, and expect that it might have a bit of a delay to the normal back-to-school season inventory build-up."

Android Wear is getting a new update today that's easily its biggest yet. Google's introducing several new features that change how we use our watches, from Wi-Fi support to hand gestures and hand-drawn emoji. Individually, these changes are small, but collectively, they promise to make even year-old hardware seem new. They also ensure that Android Wear keeps up (and in some cases surpasses) the Apple Watch from a pure features perspective. That could become important down the line should Google’s plans to release Android Wear for the iPhone come to fruition.

Sortix is a small self-hosting Unix-like operating system developed since 2011 aiming to be a clean and modern POSIX implementation. There's a lot of technical debt that needs to be paid, but it's getting better. Traditional design mistakes are avoided or aggressively deprecated by updating the base system and ports as needed. The Sortix kernel, standard libraries, and most utilities were written entirely from scratch. The system is halfway through becoming multi-user and while security vulnerabilities are recognized as bugs, it should be considered insecure at this time.

Sortix 0.9 was released on December 30, 2014. It is a very considerable improvement upon Sortix 0.8 and contains significant improvements all over the base system and ports. The previous release made Sortix self-building and this release works hard towards becoming fully self-hosting and installable. Several real-life prototype self-hosting installations of Sortix exists right now, I expect the following 1.0 release to make real Sortix installations available to the general public.

Windows Phone fans pining for the days of Metro panoramas and integrated experiences have had a tough couple of years, with Microsoft steadily removing many of the platform's user experience differentiators. But as I've argued, there's reason behind this madness. And now an ex-Microsoft design lead who actually worked on Windows Phone has gone public and agreed with this assessment. You may have loved Windows Phone and Metro, but it had to change.

Rumors of a Microsoft and Cyanogen partnership have been making the rounds recently, and the Android mod maker is confirming them today. In an email to The Verge, Cyanogen says it's partnering with Microsoft to integrate the software giant’s consumer apps and services into the Cyanogen OS. Bing, Skype, OneDrive, OneNote, Outlook, and Microsoft Office will all be bundled later this year. As part of the partnership, Microsoft has committed to creating "native integrations" on Cyanogen OS.

The European Commission has been examining Google’s Android operating system for nearly three years, and it is now ready to launch a formal investigation into claims of unfair app bundling. Google services and apps like Maps, Chrome, and YouTube are often bundled with Android devices, and competitors have complained that it’s giving Google an unfair advantage. Regulators previously questioned telecom companies and phone manufacturers, to see whether Google forces them to bundle apps or services at the expense of competitors.

The combined company will have unparalleled innovation capabilities, with Alcatel-Lucent's Bell Labs and Nokia's FutureWorks, as well as Nokia Technologies, which will stay as a separate entity with a clear focus on licensing and the incubation of new technologies.

Google will on Wednesday be accused by Brussels of illegally abusing its dominance of the internet search market in Europe, a step that ultimately could force it to change its business model fundamentally and pay hefty fines.

Margrethe Vestager, the EU's competition commissioner, is to say that the US group will soon be served with a formal charge sheet alleging that it breached antitrust rules by diverting traffic from rivals to favour its own services, according to two people familiar with the case.

The FCC officially published its new net neutrality rules to the Federal Register yesterday, opening the door to legal challenges. Opponents wasted no time. CTIA, the trade association that has represented the wireless industry since 1984, filed a lawsuit with the DC Circuit Court of Appeals today. In a blog post, the group wrote that it intends to push back against "the FCC’s decision to impose sweeping new net neutrality rules and reclassifying mobile broadband as a common carrier utility." The National Cable and Telecommunications Association and the American Cable Association also filed suits along similar grounds.
