Apple is exploring new headsets and smart-home devices to expand its lineup.Its plans don't always work out;it scrapped a car project and faces weak demand for the Vision Pro.Apple's future profits depend on the success of devices other than the iPhone.Apple's possible future product lineup suggests the giant is entering a new era.Many devices are reportedly in the works at the tech giant, and many of them are very different from its golden child, the iPhone. Apple followers including the Bloomberg reporter Mark Gurman and the Taiwan-based supply-chain analyst Ming-Chi Kuo have said it's exploring new headsets, smart-home devices, and more.The tech industry has long speculated about Apple's next big thing. The answer may lie in the slate that people have been reporting on for the past several months.Creating a hit product isn't easy. The company in February scrapped plans for a car, and its $3,500 Vision Pro has gotten mixed reviews in the months since its release. On November 10, Gurman said Apple was focusing on smaller wins that could generate revenue on the same level as its iPads or wearable tech.That requires Apple to tiptoe into new territory where competitors may already be making strides.Bloomberg, also in November, reported on a wall-mounted smart-home tablet in Apple's production lineup that could operate home appliances, use Apple Intelligence, and access Apple apps.The report said the project, code-named J490, could come as early as March, a month before new Apple Intelligence features are expected to roll out.Though smart-home tech isn't a cash cow for Big Tech, another futuristic smart-home device is said to be on Apple's radar: a tabletop robot with an iPad-like display and a robotic arm.Analysts from Morningstar, Deepwater Asset Management, and EMARKETER were skeptical about the device's profitability or the probability of its existence when Business Insider asked them about it in August.Apple is also reportedly developing a smart lock and doorbell system, Bloomberg reported on Sunday. The device would allow a person to open their home's door by scanning their face, the report said. It's unclear whether the doorbell system would work with existing third-party locks or if the company would partner with a lock maker.The technology could certainly introduce competition to Amazon's Ring and Google Nest. However, the report said it's unlikely the product would launch until the end of 2025 at the earliest.Meanwhile, Kuo, known for his often accurate Apple product predictions, said in early November that the tech giant had delayed production of a cheaper Vision Pro to "beyond 2027" and would move ahead with a Vision Pro with its M5 processor and Apple Intelligence for 2025.In the wearables category, Apple is said to be exploring AR glasses perhaps inspired by the prototype Orion glasses Meta showed off in September though they're far from production stages. The Morningstar analyst William Kerwin previously suggested that smart glasses are likely Apple's ultimate eyewear goal.CEO Tim Cook, who's been in the role for 13 years, is guiding the company into a new future. The next line of products Apple launches could solidify his legacy.
