You may not have heard of Capgemini, but the technology consulting firm has some big-name clients, like drug maker Eli Lilly and the accountants PriceWaterhouseCoopers — big corporations that spend big money on office software and technology. So it's no small deal that Capgemini is endorsing Google's suite of office software. Capgemini will continue to support business software made by other vendors, including Microsoft and IBM, but this is the first time one of the world's top technology consulting services will recommend Google Apps to its corporate customers.
