Someday, this whole operating system fan war will end and you may not even require an operating system at all to run the things you need. This idea is called "cloud computing" and Google's doing all it can to try and streamline this idea. The Pano Zero Client apparently has the same idea - no operating system, no software, nada. Basically, it's meant to be used only through a network connection where you can basically do all your normal day things. The only difference is that you'll be in the "clouds," consuming about 3% of a normal PC's power, feeling all good and green about yourself.
The idea is pretty bold and we're probably going to need to keep a close eye on it in case it explodes like the whole "netbook" revolution. It's an interesting concept - to be able to work completely without having to purchase expensive hardware to run the latest and greatest software. Surely, it'll cut down on wastes for everyone and the meaning of "green" might actually start to truly go into effect.
The computer does have the bare basics - a VGA plug and a USB hookup, as well as audio in/out jacks.
