As Jolla gears up for the imminent unveiling of its first smartphone packing the MeeGo-inspired Sailfish OS, there's been another shake-up at the highest level of the company. Marc Dillion will no longer be CEO as of May 6th, with a man by the name ofTomi Pienimäki taking over leadership of the company. He's no stranger to Jolla -- he's an investor and his brother Sami is one of the company's founders. Using nearly the same wording as when previous CEO Jussi Hurmola changed roles, Dillon will now be able to "fully concentrate on the development of Sailfish operating system" under his new title of Head of Software Development.Pienimäki's record shows he's all business, with experience in management, logistics, supply chains and driving growth -- you know, all the fun stuff that keeps a company ticking. Following the handset reveal in May, Jolla expects to start a "pre-sales campaign" in the same month and have devices available for purchase during the second half of this year.
