they should've added hearing, not touch.
Actually WIndows 8, like it's predecessor, includes speech recognition - and it's a perfect example of how half arsed the update is.
The first thing you'll notice when setting it up is the tutorial. It's entirely unchanged from the Windows 7 version, and includes diagrams showing the Windows 7 Start Orb and Start Menu that no longer exist. You're told how to turn off the PC by issuing the commands:
"Start"
"Shut Down"
"Turn Off"
If you try this however you'll find that Metro has completely buggered this up. The actual sequence as near as I can tell is now this:
"Start" (Return to metro start screen)
"Press T" (To start a search)
"Settings" (To search settings)
"Delete All, Turn Off Your Device" (To search settings for the correct item - it's easier to just delete the original T)
"Show Numbers, Two, OK" (You can't select the search result any other way. Saying "Turn Off" etc just adds the text to the search again)
At this point you now finally have the settings side bar up with the "Power" button available. You might think saying "Power" will get you there. It won't - apparently the side bar doesn't have whatever accessibility hooks are needed by speech recognition, so it's back to:
"Show Numbers, Five, OK"
"Turn Off"
