The UbiDuo is a portable stand-alone communication device with two halves that can be carried anywhere at any time. There is no need to look for another computer, tablet or cell phone for your chat partner to use. IM does not provide the same real-time conversation experience as the UbiDuo. With IM, a person has to type a line of text and then hit Enter to send it to the other party. IM is not much different from writing notes back and forth, except that networked computers are used instead of paper and pen. The UbiDuo enables simultaneous real-time conversation. At the moment a key is pressed, it is immediately transmitted to the other half for display. There is no need to press Enter, and each partner can type and read at the same time. Also, there is no need to be connected to a network in order to use the UbiDuo, since it has its own built-in wireless network.← How is the UbiDuo different from instant messaging (IM)?
