Apple relies for much of its success on its chief executive officer and founder, Steve Jobs, and his products.
Jobs was back on the stage Monday unveiling another product: iCloud, a service that will store users' music, photos, documents and more online. Jobs, who appeared extremely thin at the announcement, has been on medical leave for the past five months.
CBS News Correspondent John Blackstone reported the company's CEO appeared only briefly before turning much of the presentation of the company's software updates over to other executives.
Stock prices fell following the Apple event, , CBS News Business and Economics Correspondent Rebecca Jarvis reported.
Is this a harbinger of hard days to come for the tech titan?
Jarvis said the stock price movement didn't necessarily have anything to do with the way Jobs looked.
"Anytime Apple makes a big announcement, the stock runs up in advance of the announcement," she said. "Oftentimes, what happens is the stock gets sold. The reaction is, generally speaking, a little bit muted, unless there's something bigger, unless there's some sort of 'Oh, my goodness, the company failed here.' People don't think Apple failed yesterday. They think it's an interesting idea, the whole iCloud, the whole making music accessible anywhere, anytime."
However, Jarvis said, the company did not introduce a new iPhone.
"There was speculation that there may be a new iPhone in the announcement," she said. "Analysts and investors didn't get that announcement. That's another component of what happened. It fell about one percent yesterday. Not a significant fall, but a fall."
According to Apple watcher Neil Ticktin, the Jobs' short appearance at the event may be a sign of succession planning.
Ticktin, of MacTech magazine, said, If something, God forbid, were to happen to Steve, I think Apple is in really, really good hands."
Apple is aiming iCloud at those who have or hope to have an iPhone, iPad and an Apple computer. With iCloud, everything that is on one of these devices will automatically be on all of them.
Jobs said at the conference, "Keeping these devices in sync is driving us crazy."
With iCloud, which will be offered free, Apple is pushing its advantage as a maker of both hardware and software in the competition with its big rivals, Google and Amazon.But will the iCloud take off with consumers?
Jarvis said consumers seem to need to build trust in this service.
"It reminds me of when online banking first began," she said. "People are apprehensive. You put your music out there for Apple to store on the servers, all of a sudden you're giving up the control and giving it to an un-faced individual."
She explained, "When you put your music on the Internet and you don't have it on your hard drive anymore, that changes what kind of access you have to it and also who else has access to it. I tweeted about this yesterday, and a lot of people came back and said, 'I don't know if I want to cede all of that control to Apple.' And some people tweeted back, online banking was the same way, people didn't want to go online and give up all of that personal information."
