According to a report by Japanese writer Nobuyuki Hayashi, Steve Jobs was interested in equipping Sony’s VAIO laptops with OS X. After the company had moved from PowerPC to Intel, Jobs had approached ex-Sony president Kunitake Ando in Hawaii. The timing, however, was bad. Sales of the company's Windows-powered laptops had just begun taking off, and the negotiations to make Mac-compatible VAIO's ultimately came to nothing.
