Dell's mobile president Ron Garriques today signaled he was leaving the company as part of a reorganization of its phone and tablet plans. The Texas PC builder is merging the communication solutions section into its individual home, business, enterprise and government sections, eliminating the need for a separate mobile group but not necessarily Garriques himself. The executive will stay in his role until the end of Dell's fiscal year in January 31 and consult the company for the rest of that year.
