Software: The Softer Side of Sears

File this one under "Signs of the Times." Sears plans to convert some shuttered or underperforming stores into data centers. The retail giant formed a new subsidiary last March called Ubiquity Critical Environments LLC, which is chartered to convert selected Sears and Kmart properties into data centers - complete with servers, coolers, and back-up generators. Ubiquity also intends to rent rooftops to telecommunication companies.
