And a refresh of the Mac desktop line boasts seven colour options, hearkening back to the famous candy-coloured Macs that helped Steve Jobs revive the company in the 1990s.

The announcements show how the iPhone maker is accelerating the expansion of its product portfolio and working to keep customers committed to its family of devices even as government scrutiny of the power and reach of major technology firms intensifies.

Most of the product introductions had been telegraphed before the presentation, which had no major surprises. Shares of Apple were down 1.3 per cent, slightly more than the 1 per cent drop in the Nasdaq index.

The new iMacs, which start at US$1,299, feature a higher quality front-facing camera and microphone, responding to complaints from consumers during the pandemic that the computer’s cameras had not kept pace with iPhones and iPads during an era of pervasive video calls.

“Apple cameras in their computers have been terrible, frankly. They finally have a reasonable camera in the iMac,” said Bob O’Donnell, head of TECHnalysis Research, who added that the new colours were likely to stand out in a market dominated by black, white and silver machines. “For right now, it feels fresh and new.”

Analysts said that when combined with Apple’s keyboard and trackpad accessories, the new iPad Pro models could be a compelling replacement for a laptop, especially for content creators or business travellers. But those accessories also push the price to nearly US$1,100 – more than Apple’s cheapest laptop, the US$1,000 MacBook Air.

Ben Bajarin, principal analyst for consumer market intelligence at Creative Strategies, said the devices are not likely to be volume sellers but will target the niche of consumers who value versatility.

“If you want to go the gamut from mobile production, content consumption and or creativity, that’s the device that does it,” he said.

Apple also announced podcast subscription services that will compete with rival Spotify Technology SA, a move to regain ground in a market it popularised years ago but never made money from.

Apple shares have risen nearly 95 per cent over the past year, faster than the 63 per cent rise in the Nasdaq Composite Index, thanks to a record US$274.5 billion in sales for fiscal 2020 as consumers stocked up on electronics during the pandemic.

The AirTags announcement could result in a new round of complaints to lawmakers that Apple is hurting smaller rivals. Tile, a private company that has sold a competing tracker for nearly a decade, last year testified before the US House of Representatives that Apple’s App Store rules had made it harder to use Tile’s products and will be called before the US Senate to testify on Wednesday.

Apple has said it subjects all apps, including its own, to the same App Store review rules, and recently allowed third-party developers to access the same systems as its AirTags.

In a research note, Raymond James analysts Chris Caso and Melissa Fairbanks said AirTags “could grow to become a US$10 billion opportunity, similar to AirPods.”

But Bajarin of Creative Strategies said that iPhone owners who come to rely the tags to help them keep track of everyday items are likely to stick with Apple’s brand over a longer time.

“The more you buy into just one hardware product, the less likely it is you’ll ever leave,” Bajarin said.
