The Apple Watch Series Five has arrived in some new countries. It is now available in South Korea, Thailand, and Brazil, AppleInsider reported.

With different local sales taxes applied, Apple is selling the Apple Watch Series 5 at roughly the same pricing as in the US in Korea and Thailand where it’s 539,000 ($458) and 13,400 ($444) respectively. It’s a considerably more expensive purchase in Brazil, however, where prices start at R$3,999 ($996). The key selling point of the Series 5 is that it brings an always-on screen that intelligently dims until you raise your wrist or tap on the screen. An ultra-low power display driver together with newly-optimized watch faces contribute to having this feature yet in theory retaining an all-day 18-hour battery life. In practice, users are finding the Series 5 battery does run down a little faster than on the previous Apple Watch Series 4, however.

Senator Elizabeth Warren has made taking on big tech a key part of her campaign for the Democratic Presidential nomination. Bloomberg Businessweek analyzed what her plans might mean.

The plan consists of two big ideas. The first is to unwind old acquisitions, such as Facebook Inc.’s purchases of Instagram in 2012 and WhatsApp in 2014. There’s a legal framework already in place for this. The Federal Trade Commission has the power to review old mergers and said when it formed an antitrust task force in February that it would consider doing so. Any such moves would certainly end up in court. Facebook Chief Executive Officer Mark Zuckerberg has already told employees he thinks the company would prevail if a Warren administration tried to break it apart. Warren’s second idea is that the tech giants—those with more than $25 billion in revenue—that operate an online marketplace or exchange shouldn’t be allowed to offer services that compete with the participants on those platforms.

On October 23, 2001, Steve Jobs unveiled the original iPod. The Economist reflected on how the device revolutionized both the music and tech industries.

The iPod’s wheel elegantly removed the scrolling problem. A tiny hard-drive built by Toshiba packed five gigabytes of memory (enough for 1,000 songs) into 1.8 inches (4.5cm), allowing the iPod to offer as much storage as any competitor in a smaller body. And the earlier launch of iTunes meant that every Apple computer had a programme dedicated to managing the device’s contents. Critics wondered whether ordinary music fans would fork out $399 (about $580 today) for such a strange contraption. By 2007 Apple had sold 120m of them, and soon launched the smaller Mini, the tiny Nano and the screenless Shuffle. The classic iPod gained a colour screen, then the ability to play videos, and finally a hard-drive of 160 gigabytes, which was more than most laptops had. Historians of Apple generally note that the iMac computer, which Jobs launched shortly after returning to the ailing company in 1997, revived its fortunes. But the iPod introduced most people to the firm’s aesthetic and technical brilliance. At its peak it accounted for 40% of Apple’s revenue.

It is fair to say IBM was not impressed with Google’s declaration of Quantum Supremacy. In post full of withering put-downs, the computer giant refuted many of the claims made in a paper published in Nature, and welcomed by Google CEO Sundar Pichai.

Recent advances in quantum computing have resulted in two 53-qubit processors: one from our group in IBM and a device described by Google in a paper published in the journal Nature. In the paper, it is argued that their device reached “quantum supremacy” and that “a state-of-the-art supercomputer would require approximately 10,000 years to perform the equivalent task.” We argue that an ideal simulation of the same task can be performed on a classical system in 2.5 days and with far greater fidelity. This is in fact a conservative, worst-case estimate, and we expect that with additional refinements the classical cost of the simulation can be further reduced. Because the original meaning of the term “quantum supremacy,” as proposed by John Preskill in 2012, was to describe the point where quantum computers can do things that classical computers can’t, this threshold has not been met.

AT&T Customers have been having voicemail issues for weeks. The Verge tried valiantly to get to the bottom of what is going on, but the situation is not getting much clearer.

AT&T has been experiencing a weeks-long voicemail outage affecting some customers across the country. But it’s hard to tell exactly what’s causing the outage, or how long until it will be fixed — and AT&T is saying conflicting things about what’s going on. Here’s what the company told us, when we asked “A recent software update to some devices may be affecting our customers’ voicemail. We are working with the device manufacturer to issue a patch to resolve this and apologize for any inconvenience this has caused.” That statement seems to suggest that only a single phonemaker is affected, and that phonemaker might share the blame for the outage — but that wouldn’t make sense, because AT&T customers are reporting a wide array of different phones are having the same issue.

In the future, the Apple Watch might have electrical and data contacts. This would allow it to do things like have a replaceable power source or additional sensors not in the watch itself. That’s according to a new patent, discovered by AppleInsider.

In a patent granted to Apple by the US Patent and Trademark Office on Tuesday for “Accessory Contacts,” the company suggests a solution could be found in the form of contacts embedded within the connector used to affix bands to the Apple Watch. According to the filing, the system would be somewhat reminiscent of the existing method of connectivity for Apple Watch bands, with a section that slides in from a side and is held in place using spring-loaded pins that pop into recesses within the Apple Watch body. A button can be pressed to pull the pin sections back, allowing the band connector to slide out.
