Cisco said in a last week that its direct sales representatives and channel partners began accepting orders for the Cius on March 31. Through the end of May, the company is delivering the devices to "key customer accounts we've identified with unique use cases," spokeswoman Molly Ford said in an e-mail interview. These companies will carry out scaled production deployments of the Cius, according to Cisco.

However, given the current upheaval at Cisco, a delay is not surprising. Last week, CEO John Chambers , and the future of its consumer-facing businesses .

Though it may end up being compared with the Apple iPad 2 in some enterprises, the Cius is not intended to go up against that device or any other consumer tablet. Cisco is aiming the product at business collaboration, with the ability to interoperate with the company's TelePresence videoconferencing system, the Cisco Quad and Cisco Show social-networking platforms, and the company's WebEx online meeting system. The Cius, which is based on the Android 2.2 operating system, is also designed to run business applications.

The Cius has a 7-inch screen and a 1.6GHz Intel Atom processor. It will come initially with Wi-Fi and cellular connectivity, Cisco has said. The company claims about eight hours of battery life. Verizon Wireless said in January that it would begin selling the Cius for use on its 4G LTE (Long-Term Evolution) network in the spring and would be the first carrier to offer the tablet.
