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.

“We are no longer planning to pursue the acquisition as there has been no progress since we withdrew our offer as of Oct. 22, 2008,” the company said in a filing with the Korea Exchange. The announcement comes after the two companies inked a new seven-year NAND flash-memory license agreement, one that will see Samsung paying about half the royalty amount it paid previously.

And thank God for that adjustment. Because without it, SanDisk’s Q4 loss weighed in at a porcine $1.86 billion, or $8.25 a share, thanks to a $1.02 billion pretax goodwill and intangible asset impairment charge.

Suffice to say, SanDisk (SNDK) isn’t optimistic about its prospects in the months ahead. “First Quarter and 2009 visibility continues to be poor as seasonally soft demand is being aggravated the global recession,” Harari said in an earnings release. “With dismal Q4 and 2008 results reported by all Flash competitors, the Flash industry is at a crossroads. Three consecutive years of price reductions exceeding cost reductions have squeezed profitability out of this industry, even for the most competitive suppliers and this has been exacerbated by the global economic recession. Although 2009 is shaping up to be another tough year, we are very encouraged by the deep production cuts by the industry that we see as leading to the return of balanced demand and supply and improved pricing environment and much healthier growth for the survivors in 2010 and beyond.”

Key word here being “survivors.”

This morning the company announced slotMusic, a compact memory card-based music format that can be played on cellphones, PCs and some MP3 players. It relies on MP3s without digital rights management schemes and is backed by Universal Music Group, Sony BMG Music Entertainment, Warner Music Group and EMI Group, all of which apparently believe that more physical media is the best way to reinvent their business model in the era of digital distribution. Though as SanDisk VP Daniel Schreiber notes, they do have their reasons. “There’s a billion phones out there and a lot of them can play music and a lot of them have a microSD slot,” he explained. “We think there’s still a need for a tangible, physical product. People will appreciate walking out of the store playing music on their phones.”

Perhaps. But will they appreciate carrying that music around on a 0.6″ x 0.4″ medium that’s about the size of a fingernail? Seems easy to lose, doesn’t it (maybe Case Logic is planning a slotMusic binder)? And wouldn’t they rather carry around hundreds of songs, instead of the dozen or so stored on each slotMusic card? And what if the memory card in their phone is already in use, filled up with contacts, applications and other data? What then? And beyond this, haven’t iTunes and Amazon MP3 made consumers more accustomed to purchasing music à la carte? Why purchase a full album at $15, when all you really want are the only two good songs on it?

Is SanDisk out of its mind?

On Tuesday the company rejected a $5.9 billion acquisition bid by Samsung Electronics. Apparently, it feels the $26-a-share cash offer–an 80 percent premium over its Monday close–undervalues the company. Which may have been true once upon a time. But now that a supply glut has depressed prices for the memory cards on which its business is built and its shares have lost half their value, well … really, you have to wonder what the company is thinking.

Anyway, Samsung isn’t taking no for answer. In a letter to SanDisk CEO Eli Harari Wednesday, Samsung CEO Yoon-Woo Lee argued that a merger is a financial win for both companies.

Our many meetings and conversations over the last several months have served to confirm for us that a combined Samsung-SanDisk would have a superior global brand, an unparalleled technology platform and the scale and resources to drive convergence in the marketplace. With SanDisk’s innovative culture and technology leadership and Samsung’s scale, leadership in manufacturing and execution, and strong systems and consumer electronics segment knowledge, the combined company would be well positioned to accelerate the adoption of flash memory technology in new markets. We can also establish the platforms and capabilities necessary to position flash as the preferred vehicle for delivery and storage of a wide variety of content, such as film, in a way that would not be possible for either of our companies alone.

As we have seen in recent months, markets have become more turbulent and global economic trends are negative. At the same time the competitive environment remains challenging. To survive and compete in these times we will each need to leverage our resources and rely upon a strong balance sheet to fund critical investment and development through good times and bad. Separately investing in necessary state of the art facilities will be a significant tax on your business in the near term. In addition, reliance on IP and enforcing it is a costly and uncertain business for both our companies. Faced with these challenges, now is the time to merge.

A persuasive argument. But not in the eyes of SanDisk (SNDK), which seems determined to play Yahoo (YHOO) to Samsung’s Microsoft (MSFT) and, in Lee’s words, “continues to cling to unrealistic expectations on both its standalone market value and an appropriate merger price.”

Now SanDisk. Today, NBC U said it would make its shows available on SanDisk’s recently launched Fanfare PC-to-TV video player service. Come January, consumers will be able to download episodes of NBC series they can no longer purchase on iTunes, and transfer them to their TVs via SanDisk’s TakeTV product.

“Fanfare is going to be an iTunes-like store for us,” NBC U’s president of digital distribution, Jean-Briac Perrette, told Silicon Alley Insider. But with one noteworthy difference: NBC U controls pricing. “The business model is one we like,” said Perrette. “It’s normal for content owners to control the wholesale price of their content. This is no different than any other wholesale relationship; it’s not different in the sense that Wal-Mart decides to price DVDs at a loss. Ultimately we still set the wholesale price.”

SanDisk filed three patent-infringement lawsuits against 25 companies that make, sell or import USB flash drives and other removable flash storage products yesterday, seeking damages and a permanent exclusion order from the U.S. International Trade Commission banning importation of infringing products into the United States.

SanDisk hasn’t yet disclosed publicly the patent(s) at issue here–and there are certainly a number of possibilities– but No. 5,602,987, Flash EEprom system may be one of them. After all, the company has used it for these purposes before.

Anyway … Among those on the receiving end of SanDisk’s suit: LG Electronics, Buffalo, Corsair, Kingston, Verbatim Transcend and Imation/Memorex. “These actions demonstrate SanDisk’s long-term commitment to enforcing its patents, both to protect our investment in research and development by obtaining a fair return on that investment, and out of fairness to third parties that participate in our patent-licensing program,” E. Earle Thompson, chief intellectual property counsel at SanDisk, said in a statement, noting that defendants named in SanDisk’s suits would be offered the chance to participate in its patent-licensing program. “Otherwise, we will aggressively pursue these actions, seeking a prompt judicial resolution awarding damages, obtaining injunctive relief and banning importation of infringing product.”
