Lenovo -- home of the hallowed ThinkPad -- is hopping into the renewed all-in-one craze with its own entry into the field, the IdeaCentre A600.

Formally unveiling at CES this week, the product will hit the market (tentatively) in April.

Featuring a 21.5-inch screen (with an 16:9 aspect ratio), the A600 boasts a thickness of just 27mm, which Lenovo claims makes it the slimmest all-in-one PC on the market. I can't verify that claim explicitly, but I'm hard-pressed to name a thinner all-in-one.

Many of the ThinkPad's standard features are also available on the A600, including face recognition security, the Lenovo rescue system, Dolby-certified audio, and a nearly-edgeless display design that takes the screen almost all the way to the corners. The A600 also includes touch-sensitive controls and an "air mouse" (with additional DVD/TV/media center features) that allows for table-free control. The remote also doubles (triples?) as a wireless VOIP handset for making Internet phone calls; now that's a cool idea.

A Blu-ray drive and a TV tuner are both standard.

Pricing was not immediately available, but I love the look of the A600 and its high-end feature set (up to a 1TB hard drive, 4 gigs of RAM, etc.). Can't wait to see one in the flesh!
