voice control (an accessibility feature for now) lays the groundwork for more pervasive computing for all, but mouse support fills a hole until that happens.

i don't think voice control will replace physical controls, but do think it will grow in usage over time to become an important augment to physical controls.

now i'm just waiting for pervasive handwriting input with realtime OCR and indexing (for instant search), which can replace all sorts of note-taking and annotation workflows (and the requisite printing to paper that now often entails).
