With its customary flair for sexing up the art of gizmo glorification, Macworld 2009 didn’t disappoint with some big reveals today.

Topping all the charts was Apple’s latest update to its iLife suite, touting major retrofits of iMovie, iPhoto and GarageBand. The changes range from a better system for organizing photos in iPhoto to more powerful video editing functions in iMovie to a series of learning tutorials for various instruments in GarageBand.

“iLife continues to be one of the biggest reasons our customers choose to get a Mac,” said Steve Jobs, Apple’s CEO, in a statement. “With iLife ’09, we’ve made working with photos, making movies and learning to play music a lot more fun, and iMovie users are especially going to love the advanced but easy-to-use new features.”

Right after the big iLife news hit, Sling Media introduced a real stunner: HD streaming for Macs and iPhones via Sling.com. Sling Media expects to have an iPhone app out soon. Expected release date for SlingPlayer, a downloadable application that will interface with Sling.com to deliver HD content, is sometime in the first fiscal quarter of this year.

“SlingPlayer Mobile is ideally suited for the iPhone’s large touch screen display and I know iPhone users are eagerly anticipating the application’s availability,” said Blake Krikorian, co-founder and CEO of Sling Media.

Following up, a new 17-inch MacBook Pro with unibody construction and a non-removable 8-hour life battery and an optional anti-glare coating on the screen was announced. The computer comes packed with a 2.66ghz Intel Core Duo chip, a 320 GB Hard Drive, and 4 GB of RAM, to name a few updates.

“We’ve developed new battery technology that is better for the user and better for the environment,” said Jobs. “Apple’s advanced chemistry and innovative technology deliver up to eight hours of use on a full charge cycle and up to 1,000 recharges.”

The final move of the day set social networking sites buzzing. Apple announced a new DRM free iTunes with a three tier pricing structure — $0.69, $0.99, and $1.29.

Both moves on the iTunes front were widely regarded as a necessity in order for iTunes to remain competitive with other online music stores, with the DRM removals hailed as long overdue.
