Apple’s next unveiling could make or break a business

These annual iPhone unveilings have become a sort of Creative Destruction Day in Silicon Valley. Remember all those companies that were making nifty little digital video recorders? There aren’t many of them left, after Apple added video recording to the iPhone in 2008. And with every even slightly improved iPhone that adds features or services offered by others, Apple has tightened the screws on a long list of companies, including other smartphone makers like Nokia and BlackBerry and gaming companies like Nintendo.
