Some thrills, some spills kick off CES 2012

CES 2012 doesn't open to the public till Tuesday, but the product announcements and leaks are already flowing. Check out some of the worthy and not-so-worthy gadgets here.

LAS VEGAS--The booths are still empty and the crowds of people have yet to arrive, but make no mistake, CES 2012 is already rocking and rolling.

The show doesn't open to the public till Tuesday, but a number of leaks are already stirring up some excitement. In addition, several companies held events today that yielded some highs and lows.

Acer was the first to kick things off, and unfortunately, its announcements were rather lackluster. The company unveiled the Timeline Ultra and Aspire S5 ultrabooks, as well as its AcerCloud service. Acer also teased a new tablet with the highest resolution screen to date, but then failed to provide many details about it.

Lenovo kept the ultrabook party going with the introduction of the 14-inch IdeaPad U310 and U410. Available in a rainbow of colors, the ultrabooks differ from last year's IdeaPad U300 model by using a standard hard drive, instead of solid-state drive.

Lenovo's show stealer, though? The K91Smart TV, the first TV to run Android 4.0 Ice Cream Sandwich. Perhaps beating Apple to the punch, the 55-inch 3D LED is expected to be available in China first (no release date though) and features Qualcomm's 8060 Snapdragon dual-core processor, a 5-megapixel Webcam, and voice control, among other things.

Meanwhile, Toshiba wowed us with the Excite X10, the thinnest tablet yet, and then immediately burst our bubble by revealing its ridiculous pricing.

It wasn't all about ultrabooks and tablets, though. A new 3D printer by Cubify will soon allow you to bring your creations to life. The Parrot AR.Drone quadcopter is now equipped with a 720p camera for all your spying needs, and hardware and software improvements should make it easier to fly.

Of course, there is plenty more to come. Monday is Press Day, and with more than 18 companies scheduled to hold events, the news will be coming fast and furious. CNET is live-blogging and streaming many of the events, so check this calendar for a full schedule. We'll also be wrapping up each day's highlights here on Crave, so be sure to check back often.

Until then, here is your CES moment of zen.
