Apple’s iPhone, birthed last summer, is a force to be reckoned with. Combining a mobile phone with a digital music and video player, handheld photo album and full-strength Web browser, it’s a great device. A new version was announced June 9 and is likely to stoke even more “iMania,” given that it has a lower price and more features than the original. Roughly 6 million iPhones are already in circulation, and Apple chief executive Steve Jobs has forecast 10 million iPhone sales for 2008; Apple says 1.7 million were sold in the first quarter.
