Samsung took a hit this weekend as CTO Omar Khan confirmed that he was leaving the company. The executive, best known for the very recent Galaxy S II and Galaxy Tab 10.1, is quitting to join Citigroup as the company's worldwide mobile analyst leader. He told The Droid Guy that he starts at the new role next week and will see some of the public relations-related parts of his work shouldered by Gavin Kim and Nick Dicarlo.
