The Asus P5E3 [email protected] motherboard has a special boot sequence (ExpressGate,SplashTop) which loads an embedded Linux Operating system with Firefox and Skype pre-configured. The system will be up and running in quick 5 seconds. Quite handy when you quickly want to browse the Internet or grant a guest access for someone to your PC.
Hopefully, this technology would become cheaper soon. I would definitely want this feature on my next Laptop.
