The I/O limit could be on memory. Servers can have >1000 times more RAM than there is cache on a CPU chip. With enough threads and/or processor cores the cache hit rate drops, so that the memory bus is 100% busy. At that point a faster CPU gives no benefit, may as well us a low-power one.

Maybe the person adding the new key didn't pay for the device. It may have been borrowed by police or black hats for spyware installation, or it may have been outright stolen. Requiring secure boot can protect the legitimate owner of the device in these cases if the owner has taken reasonable steps to prevent access without proper authentication.

Another valid reason for preventing unsanctioned OS's to run on the device is to prevent reverse engineering. This enhances (through obscurity) the security of any secondary encryption or authentication that applications on the device may use.

Secure boot is the first step in loading a trustworthy computing environment. Content and media companies will be more willing to license their content for use on secure Win8 machines because they can be sure that the content can't be easily copied.

Content not available on other devices, or only at higher prices / lower quality, is a killer app for Win8. Another one would be widely available and used IP-based voice/video communication, which Win8 will probably have (based on Skype).

Morlenden (108782) writes "Whether or not climate change is caused by human activity, there are several other ecological problems caused by a increasing human population. A constant focus on climate change leaves these other problems un-addressed, perhaps leading to problems ahead where the carrying capacity of the Earth is reduced by ecological damage even while the human population continues to increase."

Living on Earth may be expensive, but it includes an annual free trip around the Sun.
