Sony all-in-one PC doubles as high-def TV

Sony on Monday introduced its Vaio LT HD PC/TV, an all-in-one computer designed to appeal to users who want their computer to do double-duty as a TV. It will be available in October starting at $1,900.

The all-in-one design and widescreen 22-inch display is evocative of Apple's iMac, but the Vaio LT sports some distinct differences. It can support a CableCard, for example, which allows the unit to work in conjunction with premium digital cable television service. An "HD" model is also available for $2,900 that adds Blu-ray Disc playback and burning capabilities.

Because it's designed to work as both a computer and a TV, the Vaio LT sports an A/V power switch that lets you shut down the TV circuitry while still operating it as a computer. The system keeps wires to a minimum by including a wireless keyboard and mouse.

The Vaio LT is encased in a transparent polycarbonate frame and sits on a horizonta surface using an integrated kickstand. It can also be mounted on the wall using a VESA-compatible mount.

The Vaio LT features a 1.3-megapixel built-in webcamera and microphone. It uses an Intel Core 2 Duo microprocessor and 2GB of RAM, and features Microsoft Windows Vista Ultimate and a discrete graphics card. It incorporates a built-in wireless 802.11n wireless networking card.
