The 2013 Consumer Electronics Show is underway and companies like Samsung, Lenovo and Nvidia have already revealed a host of new products. CES is a trade show held in Las Vegas, NV featuring products from 15 consumer technology markets.

Lenovo revealed the IdeaCentre Horizon, a 27-inch tablet that transforms into a desktop. The tablet runs both Windows 8 and Lenovo’s own Aura software.

Nvidia, a computer graphics company, also introduced Project Shield, a gaming handheld with Nvidia’s Tegra 4 processor and powered by Android. The system includes a controller and screen complete with microSD, microUSB, HDMI and audio jack ports.

Samsung announced a series of new products including a multi-view TV, a smart refrigerator and updated cameras.

Two of the TVs Samsung presented included a 55-inch OLED TV with multi-view and an 85-inch ultra-high-definition TV. Samsung’s cameras included more sharing features and the ability to shoot 3-D video and still photos.

The Samsung T9000 refrigerator has an LCD screen that lets you share lists on Evernote and use weather and calendar apps.

Qualcomm CEO Paul Jacobs gave the keynote speech at CES and was joined by Microsoft CEO Steve Ballmer.

Ballmer discussed Microsoft’s new Windows RT and Windows 8 devices. “The new Windows Phones are incredible,” he said. “In November, we reported that sales were four times greater than the same time last year, and during the week of Christmas, we sold five times more phones than the same week last year.”

Jacobs announced two new quad-core Snapdragon processors from Qualcomm, the 800 and 600 series.
