According to Cross, Jobs had "a healthy spring in his step," his "voice was strong, it sounded like him on stage," and "he had a nice smile on his face." Jobs' most recent leave has raised uncertainty for Apple, as he is closely identified with the company and turning its fortunes around over the last decade. As he did during Jobs' prior medical leave in 2009, Tim Cook, Apple's chief operating officer, will run day-to-day operations at the company. Still, according to some analysts, Apple's foreseeable future remains bright with or without Jobs.
