According to Chicago Business, Google is looking for more than 500,000 square feet of office space in downtown Chicago to house Motorola Mobility — currently based in suburban Libertyville — which could hold about an estimated 3,000 employees. It's a curious move considering that the companies could benefit from cozying up together in the San Francisco Bay area, but then, there are plenty of other telecoms in the Windy City: Tellabs, Motorola Solutions, and Alcatel-Lucent, just to name a few. It's also no guarantee that Google will hold onto the company in the long run, but it's nonetheless an interesting decision to look at real-estate in the midst of the ongoing acquisition.
