In 2010, OLPC moved its headquarters to Miami. The Miami office oversaw sales and support for the XO-1.5 laptop and its successors, including the XO Laptop version 4.0 and the OLPC Laptop. Funding from Marvell, finalized in May 2010, revitalized the foundation and enabled the 1Q 2012 completion of the ARM-based XO-1.75 laptops and initial prototypes of the XO-3 tablets. OLPC took orders for mass production of the XO 4.0, and shipped over 3 million XO Laptops to children around the world.
