WHAT’S TIM COOKING UP? Apple CEO Tim Cook, sitting for the opening interview at the D: All Things Digital conference yesterday in Rancho Palos Verdes, defended the company's prowess as a tech trend-setter, countering recent complaints that the tech giant has failed to introduce any groundbreaking products during the post-Steve Jobs era, The Wall Street Journal reports. Most of Cook's speech was dedicated to defending Apple's prowess as a tech trend-setter, amid "We have several more game changers in us" that the company has been "working on for a while," Mr. Cook said at the event. Cook praised devices like Nike’s FuelBand, a bracelet that tracks physical activity, asserting that wearable products "could be a profound area for technology." Shockingly, he was unenthused about Google Glass, saying it's "tough to see" the high-tech eyewear having mass-market appeal (what a quipster). Cook also disclosed that Apple had hired Lisa Jackson, who served a controversial stint as head of the Environmental Protection Agency, to oversee the company's environmental policies. In a statement provided by Apple, Jackson said, "I'm incredibly impressed with Apple's commitment to the environment and I'm thrilled to be joining the team."
