If this is instant boot, I am hoping it is not like Asus' ExpressGate. I am also hoping that this will not a be a limited OS for that fast boot. Also as others have mentioned, how much of a battery difference there is.
Its probably another lame Linux OS that has very limited use. I have a Lenovo S10e with a similar useless product. I ended up uninstalling it because it would actually cause Windows to boot slower because it wants to boot first. I just don't see the point?
