Unfortunately, after a week of intense testing of the service, I can’t recommend it, at least not in its current state. It’s a great idea, but, as of now, MobileMe has too many flaws to keep its promises.

The Cupertino, Calif., company has been migrating its .Mac pay email service to an upgraded version, called MobileMe. But in doing so, it has run into problems including service outages and customers losing access to their accounts. It's the latest in a string of issues that have cropped up since the launch of the latest iPhone, an unusual turn for a company known for its attention to detail in its products and services.

Piracy can also be a source of innovation, if someone takes a product and then modifies it in a popular way. In music unofficial remixes can boost sales of the original work. And in a recent book, “The Pirate’s Dilemma”, Matt Mason gives the example of Nigo, a Japanese designer who took Air Force 1 trainers made by Nike, removed the famous “swoosh” logo, applied his own designs and then sold the resulting shoes in limited editions at 0 a pair under his own label, A Bathing Ape. Instead of suing Nigo, Nike realised that he had spotted a gap in the market. It took a stake in his firm and also launched its own premium “remixes” of its trainers. Mr Mason argues that “the best way to profit from pirates is to copy them.”
