Ubuntu is clearly taking the lead in this race. However, I am not sure this is the right approach to mobile/ubiquitous computing b/c phones brake, discharge or are lost/stolen. The best approach in my personal experience is to have terminals that connect to cloud computing services. The phone too can connect to the cloud in case a quick on the go edit/reply/action is needed. In this regard, current services already fill such need, Android and Google web apps for example. In other words, if you need to add all peripherals (screen, mouse, kb) and you most likely will also use the local LAN/WiFi (lower cost+ higher speed), then might as well add another CPU to that mix and don't depend on the phone.
