A Windows Vista computer starts and shuts down as quickly and reliably as a television, typically within 2 to 3 seconds. Windows Vista processes login scripts and startup programs and services in the background so you can start working right away. You’ll also shut down and restart your computer less often by using the New Sleep state, a simple one-click on and off experience which not only reduces power consumption, but also delivers and protects user data.
I’m extremely skeptical about this one. I couldn’t imagine a top of the line computer at that time could pull it off.. but we shall see I guess. Check it out at Microsoft. Grabbed from Digg.com.
