Apple has sold some 225 million iPods to date, making it one of the most popular electronic devices ever. And it’s sure to sell even more after the updates the company announced at this morning’s event. Among them: Larger, cheaper iPod touches and nanos with cameras and FM radios.

Following introductory remarks by Apple (AAPL) CEO Steve Jobs, Phil Schiller offers details, noting that “the iPod has 73.8 percent market share. The next biggest category is ‘other,’ and after that, SanDisk and then Microsoft pulling up the rear.”

Schiller adds that Apple has sold 20 million iPod touches since the device debuted. He runs through a lengthy sales pitch for the iPod touch, touting it as a killer pocket computer and taking potshots at rivals like Dell (DELL) along the way.

Moving on to games, Schiller notes the discrepancy between the number of games on gaming platforms like the Nintendo DS and the iPod touch. The iPhone OS, he notes, has 21,178 games. The DS has just 3,680. Point taken.

Moving on to some new game demos now. First up: Ubisoft with Assassin’s Creed 2, which, we are told, is “all about visceral combat, brutal hand-to-hand combat and one-shot kills.” Behind the presenter, a warrior is mercilessly beaten into submission.

Schiller returns to the stage, “Boy, that looks like fun.”

Tapulous, the developer of Tap Tap Revenge, and Gameloft, follow, both introducing new games. Gameloft’s Nova–a first-person shooter with multiplayer option–seems a far more compelling effort than Tapulous’s Riddim Ribbon, which appears to be a Black Eyed Peas-heavy variation of Tap-Tap.

Up next, Electronic Arts, which is apparently headlining the games section of today’s event. EA’s Travis Boatman takes the stage to introduce Madden NFL 10. The game boasts both custom-kick and draw-a-play-on-screen features developed specifically for the iPhone OS. Madden NFL 10 is available today.

Schiller again returns to the stage. “The iPod touch is the most affordable gateway to the App Store,” he says, adding that $199 is a “magic price point” in the iPod market.

With that, he announces the iPod touch price cuts we heard about earlier this morning: An 8GB model for $199, 32GB for $299, and 64GB for $399. All three devices are significantly faster, says Schiller. Interestingly, none seem to feature that rumored camera.

Price drops as well for the nano, but we knew about these. Apple has dropped the price of the iPod shuffle as well: $59 and $79. And the company is offering them in a new selection of colors. Plus, there’s a special edition of the shuffle crafted from stainless steel.

Steve Jobs returns to the stage. So those are the iPods, but there is one more thing: A video camera. He talks about the exploding video market, mentions the Flip, etc. “We want to get in on this market as well and we’re doing it for free….Boy, this really is the new Apple,” he quips.

Yes, the iPod nano does indeed now feature a video camera. The video quality looks impressive. Whoa: Apple has also added FM radio, a voice recorder and a pedometer to the nano. New polished anodized aluminum colors. 8GB model for $149, 16GB model for $179.

After a few concluding remarks about the new iPod lineup, Jobs announces what has become an annual tradition at these events: A live performance. Today’s artist: Norah Jones.

The end of her set concludes today’s event. No iPlatform. No Beatles on iTunes. But lots of product refreshes, software intros, and price cuts. Plus: Steve Jobs is definitely back.

This is a big step for Apple (AAPL), says Phil Schiller, and a big step for music. And with that, he welcomes Tony Bennett to the stage to close out Apple’s final Macworld. Bennett’s first song: “The Best is Yet to Come,” followed quickly by a second, “I Left My Heart in San Francisco.”

After a few parting words from Schiller, the keynote address ends. No jaw-dropper announcements, no cameo appearance from Jobs, but a good keynote just the same. Schiller did his boss proud, I think.

• Enhancements to Google Maps, including support for Google Street View, plus bus schedules and walking directions
• Support for over-the-air podcast updates via the iTunes Store
• An app-scoring feature that allows users to rate applications purchased from the the App Store before deleting them
• Support for line-in audio via the iPhone’s headphone jack

Wonderful additions to the platform, all of them. Of course, there are still quite a few missing. MMS support would be nice, wouldn’t it? As would support for Flash and the ability to compose messages in landscape mode.

And what about cut-and-paste? Seriously, at this point, it’s almost like Apple (AAPL) is purposely withholding it, out of spite.
