SAN FRANCISCO, MACWORLD/IWORLD 2012 — In an era when trade shows are almost extinct, Macworld is a dinosaur. And that’s in a good way.

Now in its 28th year, Macworld has survived when other trade shows haven’t. That’s largely because the show has been quick on its feet, switching focus and venues as times have changed. It’s transformed from a business-to-business show into a consumer-oriented one.

This week, the focus is entirely on end users, as Macworld attempts to rebrand itself iWorld. It will be about the Apple-oriented lifestyle, highlighting apps, art and music. Attendees can see what people are doing — or they can do themselves — with their devices.

In the video above, organizer Paul Kent talks about the transformation into iWorld. Below, he explains what to expect at the show this week.

We love Jeff Broderick’s work here at Cult of Mac. We’ve told you about some of his web app projects, like QuickWiFi and QuickContact, and his latest creation is called Photogram. As the name implies, you can use Photogram to view Instagram in your web browser. The app is beautiful and optimized for both the desktop and mobile experience.

This year’s edition of Macworld, taking place January 26-28, is shaping up to be a bit of a departure from Macworlds of the past. 2012 is a year of evolution for the event, now branded as Macworld/iWorld.

And that evolution begins tonight with a blast.

The U.S. government declared the act of jailbreaking legal on July 26, 2010, encouraging hundreds of thousands of iOS users into hacking their devices, safe in the knowledge that their actions would incur no legal repercussions. The ruling certainly had a huge on the jailbreaking community, but the tables could be set to turn once again.

According to the Electronic Frontier Foundation (EFF), jailbreaking could become illegal again this year, but you can do your bit to prevent it.

It is common for the President of the United States to honor American heroes by inviting them to the annual State of the Union address. No surprise, then, that President Obama is tipping his hat to the legacy of Apple founder Steve Jobs at tonight’s State of the Union address by inviting Jobs’s widow Laurene Powell Jobs to share First Lady Michelle Obama’s box at the event.

The event is believed to be Powell’s first public appearance since her husband’s death.

Audiobooks.com has today launched the first subscription service to provide unlimited access to thousands of audiobooks streamed directly to your device. The service uses an HTML5 web app and promises to enforce no monthly limits and no long-term commitments.

Ever wanted to quit every single open application? Perhaps you want to free up memory for the launch of another app. Here’s one way of doing it quickly and cleanly.

Siri has a new competitor, and her name is Evi. Developed by True Knowledge and powered by the same Nuance-based backend as Apple’s virtual assistant, Evi is available for all iPhones in the App Store. There’s also a beta app available for Android handsets.

While Evi doesn’t have the integrated advantage that Siri wields, she is perhaps the first clone that’s just as smart, if not smarter, than Siri.

Thanks to the newly-released Absinthe untethered jailbreak for the iPhone 4S and iPad 2, you can finally get Siri up and running on Apple’s latest tablet. The process isn’t an easy one, as you will need to set up your own SiriProxy server and edit your iPad’s filesystem.

If you have the time and stamina to get Siri up and running on the iPad 2, you’ll be able to take advantage of all the voice assistant goodness that’s available on the iPhone 4S. You’ll also be able to install other jailbreak tweaks to enhance Siri’s functionality.

If you thought there would be little interest in an Apple event that didn’t include new hardware, think again. Following the unveiling of iBooks 2 with support for textbooks last week, Apple saw an incredible 350,000 textbook downloads in just three days of availability.
