Having a fast boot time on your desktop or laptop is an important aspect of how it performs, though I think it's somewhat less important than it was in years past. Most modern computers will instead resume from sleep or hibernate mode more often than a complete reboot. Still, if you're installing a software update that requires a reboot, you want your system to be back up and running as soon as possible. The brief demo above shows you how Lenovo is tackling this problem on their Y570D laptop - the boot up is closer to 12 or 13 seconds rather than nine seconds, but it's extremely impressive nonetheless. Nicely done Lenovo!
