Share Radio's tech connoisseur Steve Caplin waxes lyrical about apple's new iPad, though not its new iMac. He admires the company's Airtags key finder, using the power of 1 billion iPhones to find any that are lost. He explains how ultra-white paint can lower temperatures, wonders why Amazon has set up a hair salon, is impressed by a 3D printable ivory substitute, wants an electric bike trailer and mulls buying a flying car despite its $789,000 price tag.
