Logitech has announced the acquisition of TT Design Labs, a Kickstarter-backed smartphone accessory maker. The company's two co-founders will be joining Logitech to help design future smartphone products, with Derek Tarnow joining full time and Zahra Tashakorina offering advice through an ongoing consulting basis. Logitech plans to further develop two of the acquired products, JustMount and TidyTilt+, and release them to customers under the Logitech brand. Meanwhile, the Logitech JustMount and Logitech TidyTilt are available for pre-order today and will ship to consumers in the coming weeks.
