In his latest Wall Street Journal column, tech guru Walt Mossberg praises Apple’s new iPod shuffle. “I’ve been testing the new iPod Shuffle for a couple of days, and, in my tests, it fulfilled–and even exceeded–Apple’s claims for convenience, battery life and song capacity. Sound quality is so good you can barely believe the music is coming from something so small,” writes Mossberg. “In my tests, the iPod Shuffle performed well, exceeding Apple’s claims. Apple puts the new player’s battery life at 12 hours on a single charge. But, in my testing, it did much better than that, lasting 15 hours and 44 minutes.”
