My new laptop has a webcam & microphone built in with Win 7.
I was surprised at how well the voice recognition worked for the navigating functions and dictations and not very many speakos/typos at all.

It will come in handy if my RSI ever flares up bad , or if I just don't feel like typing...
My desktop is still my main pc, it's just more ergo than the laptop for me.
Plus a smallish house and everyone here would hear me talking to the laptop- if they are home...
