Apple has begun taking online orders for its wireless AirPods, and said it would start delivering the $159 earphones to customers, Apple Stores, resellers and carriers next week. At the iPhone 7 launch in September, Apple SVP Phil Schiller said the AirPods would be available in October. Missing the deadline for release of any hot product is bad news for a company.

Can a new smartwatch operating system based on Linux breathe some new life into the smart wearables market? Florent Revest hopes so. Revest, a French computer science student, on Wednesday announced the alpha release of AsteroidOS, an open source operating system that will run on several Android smartwatch models. Revest has been working on his OS for two years.

Fitbit has announced an acquisition deal with smartwatch maker Pebble. It clearly has been struggling, having laid off 25 percent of its staff earlier this year, when CEO Eric Migicovsky acknowledged that money was tight. "Fitbit is acquiring certain assets of Pebble, including key personnel and intellectual property specific to software and firmware development," a Fitbit spokesperson said.

Apple drew some pointed questions this week following CEO Tim Cook's vague response to reports suggesting Apple Watch demand has plummeted. The Apple Watch is on track to set a holiday sales record and post its best quarter ever, Cook said. Sell-through of the watch -- that is, units sold to consumers and not just stocked on retailers' shelves -- also is on track to reach a new high, he added.

Fitbit, the leader in the wearables category, is close to an agreement to buy struggling smartwatch maker Pebble for up to $40 million, in a move to gain the firm's intellectual property and software. The negotiations follow several months of financial turmoil at Pebble, which reportedly slashed its workforce by 25 percent in March and has rebuffed several prior offers to be acquired.

Roku has refreshed its lineup of media players with lower prices, so bringing streaming video to every screen in your home just got a little more accessible. At the lower end, the Roku Express costs $30. The lineup includes $40, $50, $80 and $100 models with a variety of feature combinations. At $130, the Roku Ultra, pictured here, is the feature-loaded top-of-the-line option.

Snap, the company formerly known as "Snapchat," on Saturday announced sunglasses that take videos through a built-in camera in the frame. Snap's Spectacles let users take 10-second videos by tapping a button on the top left-hand corner of the eyeframe. Users can tap on the record button to record two more 10-second segments, for videos of up to 30 seconds long in all.

Apple wants to attract gaming fans to the more powerful graphics and processing power embedded in its new iPhone 7 and Apple Watch Series 2 products. The iPhone 7 features the new A10 Fusion chip -- the most powerful ever in a smartphone, according to the company. The CPU fuses two high-performance cores that run twice as fast as the iPhone 6 with much more efficient use of battery power.

Apple CEO Tim Cook on Wednesday officially unveiled the iPhone 7 and iPhone Plus, confirming a rumor that has evoked widespread dread: The traditional headphone jacks are gone. The new iPhones are sleeker than their predecessors, though, as well as water resistant. Their biggest plus might be the advanced lenses in what Apple claims is the most sophisticated smartphone camera in the world.

Fitbit on Monday announced two new fitness trackers with sleeker looks, more durable construction and greater data-gathering capabilities. The Fitbit Charge 2, priced at $149.95, features continuous heart-rate tracking. It uses the data to generate a cardio fitness score and provides guidance for improving it over time. The Charge 2 displays real-time exercise stats.

Call it a gimmick, but I'm very much into the idea of having a pizza box that doubles as a turntable. Pizza Hut partnered with Novalia to make the box, which includes pitch and volume controls, a mixer, and touch-sensitive decks. Using printed electronics, DJs can crossfade, rewind and even scratch. The box pairs with smartphones and computers using Bluetooth and works with DJ software.

Lift is an antigravity charger for Apple Watch and Pebble. The charger is wireless, so there's almost no clutter involved -- except, I suppose, when you have to charge the charger. The watch wraps around a portable battery pack, which the base keeps elevated using magnets. There's a Pro version of the base, which you can use as an iPhone or iPad stand and charger.

Concerns have been multiplying in the United States over the creaks of a medical infrastructure that's bearing the weight of an aging population. Current and upcoming members of the over-65 club are helping to drive a new age in healthcare, in which devices connect patients with caregivers, things get even smarter, and machines get even better at learning what sensors are saying.

I don't think any product range beats speakers for running the design gamut from gorgeous to ghastly. There are so many to choose from, in all shapes, sizes and colors, that there's something for everyone -- plus a few things no one should buy. But what if your sound system were a piece of art, literally? Case of Bass has created a boombox print that houses a speaker system in a shadow box.

Manufacturers are eager to lay the bricks and help pave the road to better, more personalized healthcare through integration of connected devices in the new Internet of Medical Things. Compared to other industries, healthcare has been "inherently conservative and slow" to embrace innovations such as the cloud and the Internet of Things -- but that's changing.

Lenovo has peeled back the curtain on a smartphone that you can wrap around your wrist, sporting a full-color screen. The "CPlus," as Lenovo calls the prototype, runs Android and has a 4.26-inch display. It will be available in 12 colors if and when it goes on sale. It's clear bendable smartphones will be a viable consumer product in the near future.

Samsung last week unveiled its Gear Fit2 fitness band and Gear IconX earbud set. The Gear Fit2 will be available for $180 this Friday at major retailers. The IconX will hit shelves in the third quarter of this year. The Gear Fit2 has a built-in GPS and a heart rate monitor. The Gear IconX is a pair of Bluetooth earbuds that can track fitness information.

Nokia on Wednesday announced its return to the mobile phone and tablet business in connection with a larger agreement by Microsoft to sell its entry-level phone business to HMD Global and FIH Mobile for $350 million. Microsoft will sell its Hanoi, Vietnam, manufacturing facility to FIH Mobile. Nokia will grant HMD the exclusive global license to make Nokia-branded phones and tablets for 10 years.

Smartphones appear to be losing their luster, and the king of smartphones -- Apple -- clearly is not having a good year. Suddenly, I'm hearing that there is an upswing in flip phones, making this feel a bit like a Game of Thrones episode, when a believed-dead king returns to seize the throne by surprise. Clearly, the market is looking for the next big thing.

The U.S. Federal Trade Commission and the Federal Communications Commission on Monday announced a joint investigation into the issue of mobile device security updates. The FTC issued an order requiring Apple, BlackBerry, Google, HTC America, LG Electronics USA, Microsoft, Motorola Mobility and Samsung Electronics America to provide information about how they issue security updates.

Apple on Thursday made its CareKit platform available through the GitHub open source community. CareKit joins two other Apple frameworks for developing healthcare apps -- HealthKit and ResearchKit. It was designed to enable developers to create apps that give users a more active role in managing their health. Apps developed through CareKit will let people track symptoms and medications.

Apple shares were trading at around $95 as of mid-day Thursday in the wake of the company's disappointing Q2 earnings report. That was even lower than Wednesday's opening price, which was down more than $8 from Tuesday's $104.35 at market close. The company's second-quarter performance was dismal. The iPhone recorded its first drop in sales -- to 51.2 million units, down from 61.2 million in the year-ago quarter.

Nokia on Tuesday announced plans to purchase Withings for $192 million in cash as part of its move into the healthcare devices arena. The deal is expected to close in early Q3, and Withings will become part of the Nokia Technologies business. "We have said consistently that digital health was an area of strategic interest to Nokia," CEO Rajeev Suri said.

Apple shares closed at $105.08 Monday -- down 60 cents -- as the market steeled itself for what's expected to be a gloomy quarterly earnings call on Tuesday. Apple will underperform the smartphone industry and become the only global top-five brand to see shipments decline in 2016, predicted Ming-Chi Kuo, a KGI Securities analyst who previously has made several accurate calls on the company.

Most of the changes in the next version of the Apple Watch will be on the inside and not the outside of the case, according to an investors note issued Monday by Ming-Chi Kuo of KGI Securities. His comments are consistent with rumors circulating last summer that the design of the next version of Apple's wrist computer would remain essentially unchanged.

Samsung has been granted a patent for a smart contact lens, according to news reports published last week. The lens is equipped with a tiny display, a camera, an antenna, and sensors that detect movement and eye blinks. Eye blinks would provide the input, and a smartphone would be needed to process images. A user blinks to take pictures or interact with data displayed on the smart contact lens.

Microsoft CEO Satya Nadella and members of his leadership team, speaking to developers Wednesday at the Build 2016 conference, introduced their vision to infuse human speech and machine learning into the company's consumer and enterprise businesses. Nadella and Executive VP Terry Myerson introduced upgrades to Windows 10 and Cortana as well as technology called "Conversations as a Platform."

The iPhone SE packs almost everything from the iPhone 6s into a handset that looks almost identical to the iPhone 5. The only thing that's really missing is Force Touch. It's a smart play, trying to convince iPhone 4 and 5 owners that they can still upgrade to -- almost -- the latest model without the need to take on a device with a larger screen.

Pebble -- once viewed as the little smartwatch company that could -- last week cut its worldwide workforce by 25 percent, according to news reports. That's reportedly about 40 people, but actual figures are hard to come by because Pebble is privately held. The company has raised $46 million, but CEO Eric Migicovsky blamed the layoffs on the difficulty of raising funds in Silicon Valley these days.

Microsoft on Monday unveiled its version of a teleporter, called "holoportation," which was designed to transmit 3D models of people anywhere in the world. Holoportation compresses, transmits and reconstructs the 3D scans to Microsoft's HoloLens and other head-mounted displays. It lets headset wearers interact with remote users in 3D as if they were in the same space, according to Microsoft.
