The iPhone and iPad were absolutely not a "project" (the word he uses in the article) of the past five years. They're part of a project that started more than ten years ago. I certainly don't think they're old technology - they're still ahead of the tablet and arguably the smart phone market, I think - but I don't really classify them as small projects that have a lot of potential that were just invented in the past five years. Heck, you could easily argue that the iPad is the fruition of a vision, and a project, that Steve Jobs started decades ago. And if you want to get technical, the iPhone was in active development before five years ago.
