The launch of Apple's long-awaited iPad tablet computer has been marred by reports that some users have experienced technical problems with the device. Apple sold more than 300,000 iPads on the tablet computer's first day in stores, the company said, but some new owners have logged on to Apple forums complaining that their iPad had little or no wi-fi signal, where other devices worked well. Michael Arrington at TechCrunch reported "scores of complaints" on Apple forums. "I'm getting one or two bars on my iPad in rooms where my iPhone, iPod touch, both Macbook Pros, Apple TV and Playstation all get full service," he said. The iPad can only connect to the internet via wifi. Computer experts have warned that without access to the internet "the iPad is DOA (dead on arrival)". Some suggest that the problem could be a weak wi-fi antenna, which is located behind the logo on the back of the iPad. Arrington said on his blog: "My understanding of wi-fi issues on devices, particularly cramped devices like the MacBook Air and iPad, is that it's usually a hardware/design issue and something that can't be fixed via a software patch."for further: www.telegraph.co.uk/technology/apple/7558319/Apple-iPad-launch-marred-by-technical-problems.html
