Cisco's attempt at entering the massively competitive tablet market has come to a quiet end. The company's Cius product has been set off to greener pastures without even making a serious dent in the industry. It was meant to be the leader in enterprise-focused tablets.

It's the same reason the Blackberry Playbook never got a chance to spread its wings.
