In one of the more shocking and unexpected announcements in recent memory, Steve Jobs has stepped down as CEO of Apple Inc.””the company he established in 1976 along with Steve Wozniak and Ronald Wayne””leading many to grow worrisome of his decreasing health.

Jobs has battled pancreatic cancer and other health issues over the years, one leading to a liver transplant in 2009. It’s unclear whether his health issues are in fact directly responsible for his departure as the head of Apple, but he has been on medical leave since January 17, which he said was so that he could concentrate on his health. It is for this reason that those involved with Apple and its many fans and consumers are understandably worried for the well–being of Jobs.

The man who stepped in as the CEO of Apple over the course of Jobs’ various medical leaves, Tim Cook, has once again been named the new man in charge. Jobs, however, isn’t completely stepping away from the company he’s led in making many incredible technological advancements over the years, including the iPhone and iPad, both of which are the industry standard. Jobs will remain involved with the company as a chairman of the board.

In a brief statement, Jobs said “I have always said if there ever came a day when I could no longer meet my duties and expectations as Apple’s CEO, I would be the first to let you know. Unfortunately, that day has come.”

Apple’s stock dropped as much as 7% in the hours after Jobs made the announcement, which is another major concern. Those invested in the company and consumers alike can’t help but wonder if Apple will be able to deliver the constantly evolving technologies and creative impacts they made with Jobs leading the charge.
