Here at Engadget, we don't spend an awful lot of time dabbling in operating systems, but when Phoenix Technologies offered us the chance to check out its HyperSpace instant-on OS, we just couldn't resist. After all, it's hard to ignore the allure of reported sub-10 second bootup times on portable-by-nature machines (often referred to as "netbooks," for those camped under rocks). Considering that HyperSpace is well on its way to a netbook near you (we're told that undisclosed partnerships should be completely hammered out within the next few months), why not follow us past the break to see if the system really is all it's cracked up to be.
