The mobile phone is by far the most widely available device with rendering capabilities in the world, and it is very likely that this will continue to be the case. However, this ubiquitous tool may not continue to be centered around its phone function for much longer, as it evolves more and more into a multifaceted device, which you might want to call a mobile Gizmo (see Bruce Sterling’s keynote at SIGGRAPH2004). Inevitably, graphics is becoming a core part of such a Gizmo.
