The resale market for Apple Inc.'s Vision Pro mixed-reality headset is booming, with prices reaching up to $5,000 in overseas markets, significantly above the original $3,500 price tag. The device, released in limited U.S. stores in early February, is now being resold at a premium in Japan, China, Singapore, and Hong Kong. Demand remains strong, driven by exclusivity, with analysts noting the device's potential to revolutionize the market and possibly replace tablets in the future.
