The first one is intended for netbooks and can operate only one environment or the other (Windows or HyperSpace) at a time. The Hybrid edition, which will appear on higher end notebooks instead, can run both systems side by side and lets users easily toggle back and forth between them by pressing the F4 key. However while the software will be preinstalled on Asus laptops, there is one major caveat: it will require an annual subscription.
Users will have to shell out $39.95 a year for the HyperSpace Dual setup, or $59.95 for the more functional HyperSpace Hybrid version, if they want to take advantage of this pre-boot environment. Something tells me this will be a very tough sell.
