Enderle thought the drop in stock price might have reflected disappointment that Apple didn't unveil any breakthrough devices today.
He said some thought the company might announce or tease the so-called "iPad," a much-buzzed-about, but as yet unconfirmed, touch-screen tablet.
Given Apple's dominance, he said the products the company did announce just needed to be "good enough," and the updates released today accomplished that.
The addition of the video camera to the Nano, he said, puts pressure on Cisco, maker of the Flip, a similarly small handheld video camera. It also makes the Nano more competitive with Microsoft's refreshed Zune mp3 player.
Ben Bajarin, director of consumer technology for technology consulting firm Creative Strategies, Inc., agreed that the event solidified Apple's market dominance, but he didn't think Jobs' appearance had too much of an effect on the company's share price.
"I think the overall point was -- and they've demonstrated this over time -- his surrounding cast is very capable of moving Apple forward in a direction that's good for the company, consumers and investors. But, obviously, he is the CEO. We shouldn't expect him to not show up at an event," Bajarin said.
Bajarin added that Jobs' presence was meant to emphasize his health, his engagement with the company and the importance of the iPod line to Apple's business.
The new camera-enabled Nano and $199 iPod Touch bodes well for the company, he said, and he expects to see the company's numbers rise as it moves into the fourth quarter.
