The first tablets based on Intel's processor codenamed Oak Trail started shipping late last week, with the initial models targeted at businesses.

Fujitsu's Q550 and Motion Computing's CL900 tablets have Intel's Z670 processor and Microsoft's Windows 7 operating system. The tablets have 10.1-inch screens and provide eight hours of battery life.

Working prototypes of Oak Trail tablets made an appearance in January at the Consumer Electronics Show, and the chip was officially announced in April. Companies including Acer and Toshiba showed tablets with the chip at the Computex trade show last week.

The single-core Z670 processor runs at a clock speed of 1.5GHz, and features on-chip accelerators to decode 1080p video. In addition to Windows, the chip is compatible with Google's Android 3.0 and Intel's MeeGo operating systems.

The tablets have specific security features that could make them attractive to businesses. Fujitsu's tablet has a fingerprint reader, while Motion Computing's device is bundling Absolute Software's Computrace Complete software, which helps track lost tablets. Both tablets include Trusted Platform Management 1.2 (TPM), a hardware-based cryptography and authentication technology to enhance security.

Oak Trail tablets will complete with Apple's iPad, which is finding growing interest in the enterprise. However, analysts have said that the iPad is geared more for consumers, while Oak Trail tablets will blend into IT infrastructures with compatibility for existing Windows or Linux applications.

The tablets have SSD storage and USB and HDMI slots. They also have back and front-facing cameras, Wi-Fi capabilities and come with optional 3G communication capabilities.

Fujitsu's Q550 weighs about 1.7 pounds, and is shipping worldwide. Motion Computing's CL900 weighs 2.1 pounds and is shipping in the US, Australia, New Zealand, Belgium, France and Germany.
