Jobs demonstrated the iPod nano playing video by watching an episode of The Daily Show featuring John Hodgman, the actor who appears as the PC in the US versions of Apple's "Mac and PC" television ads.
Blow-by-blow account as iPod event progresses
Jobs said the new iPod nano provides 24 hours of audio and five hours of video playback on a single battery charge.
The redesigned iPod nano comes in two versions: a 4GB version in silver, for £99, and 8GB version in colours, for £129.
"These new nanos have left our factories already. They shipped today, they're on planes, they should be in stores by this weekend," said Jobs. "'A little video for everyone'" is our new line.
160GB 'classic' iPod
"Now the iPod's got a funny name," mused Jobs. "It's just called 'the iPod' because it was the first one. We though, 'It's time to give it a name.' We're going to call it the iPod classic."
Despite rumours of an iPhone-like touchscreen iPod, the new iPod still features a click wheel, and it's now in a full metal design in silver and black. The low-end iPod classic (at 80GB) is now thinner than the 30GB thin model that preceded it. Jobs claims the new iPod gets 30 hours of audio playback and five hours of video plaback on a single charge.
Like the iPod nano, the new iPod classic features an enhanced user interface.
Apple is also offering a model that features 160GB of storage.
"This boggles the mind," said Jobs for emphasis. "The first iPod put 1000 songs in your pocket. This new iPod puts 40,000 songs in your pocket. It's amazing."
The new 80GB model costs £159, while the 160GB model costs £229, with availability beginning today.
The iPod Touch
"You know, when we introduced the iPhone in January, we said it was the best iPod ever. And iPhone owners agree with us. It's incredible, with its multitouch UI, its incredible album artwork and video, it is the best iPod ever," said Jobs. "And people have been wondering, when are we going to bring this tech to the iPod? The answer is, we're going to do it today, and this is what the product looks like."
Jobs revealed a new iPod model that looks exactly like the iPhone, but without the ear speaker slit. It's the same size as the iPhone, but 8mm thinner, according to Jobs, who said, "We think it's one of the Seven Wonders of the World."
The iPod Touch sports a 3.5-inch widescreen display, and along its bottom run music, video and photo icons. "Just like the iPhone, this is the best way to share photos on a portable device ever," said Jobs proudly.
The iPod Touch's button-driven interface also showed icons for a calculator, contacts, clock, calendar and settings icons. What's more, the new device has Wi-Fi: the iPod Touch is the first iPod to feature wireless networking capabilities, with support for 802.11 b and g networks.
"Others have done this and have failed," said Jobs, referring to wireless networking - and making a casual swipe at Microsoft's 'iPod killer,' the Zune. "We think we know why it's failed. What's the problem with adding Wi-Fi? Part is getting on Wi-Fi itself."
"When you're at home, you might need a password. When you're in the office, you might have a password," said Jobs. "But everywhere in between can be challenging. You go to any hotel, and to log in, they throw up a Web page. Portable devices don't know how to deal with Web pages. You go to an airport, you'll see a Web page. Even walking through Stanford University, to use their wi-fi, you have to log into a Web page."
The solution, said Jobs, was to add the Safari web browser to the iPod touch.
"So you can view all those Web pages, zoom in, log into any wi-fi network pretty much. But beside that, you get an incredible Web browser ... the best Web browser on any mobile platform," said Jobs. YouTube is also supported.
The iPod touch's battery lasts for 22 hours of audio playback and five hours of video playback per charge, according to Apple.
The iPod touch is a worldwide product launch, said Jobs. It's the first touch product Apple has shipped outside the US, and it's been localized into many languages.
The iPod touch is coming in two configurations: 8GB and 16GB, for £199 and £269 respectively. Both models are expected to be available "in just a few weeks," according to Jobs, who said that Apple will ship them in September, "in plenty of time for the holiday season."
iTunes Wi-Fi Music Store
"But there is one more thing, if you'll bear with us," said Jobs, who traditionally ends his product launches with a little surprise.
"You might have noticed that there's an empty spot on that dock of the new iPod touch," said Jobs. "What could that possibly be for? Well, it's for a new app we've written called the iTunes Wi-Fi Music Store."
"'Finally,' some of you are saying," said Jobs. "It's so cool. So let's take a look at what it is."
