An anonymous reader writes: Bloomberg reports: "Tony Fadell is stepping down as head of Nest Labs, just over two tumultuous years after selling the smart-home gadget maker to Google. Fadell will leave Nest immediately and be replaced by Marwan Fawaz, former executive vice president of Motorola Mobility where he served as CEO of Motorola Home, Nest said in a statement. Fadell will still advise Alphabet Inc. and Larry Page, the Google co-founder and chief executive officer of the holding company. Nest took longer than expected to release new products and a smoke and carbon monoxide detector was recalled due to software problems. When the company did release an updated product, the Nest Cam security camera in June 2015, Fadell admitted it had been a "grueling" year. In recent months, Nest employees complained publicly about Fadell’s management, while claiming the business had missed sales targets, botched upgrades and delayed future products." Fadell said, "I don't know of any regrets that I have. To do what we do at the level we do it, no one's done it before. So you're bound to make mistakes."
