In a move that confirms reports from earlier in the week, Sony confirmed that it is dropping its VAIO computer division, and will sell it to a Japanese investment fund. Sony cites “drastic changes in the global PC industry,” and the fact that they would prefer to focus on the mobile product lineup of smartphones and tablets. The investment fund will likely hire between 250 and 300 Sony employees to take over VAIO operations, and Sony will invest 5% of the new company’s capital. It’s a signal that, as far as the computer industry is concerned, Apple, and other Windows PCs, are rapidly cornering what’s left of the market, and that there’s still much growth to be had in the mobile and tablet industries as users continue to adopt differing screens.
