Yeah I read about that. Its pretty sh**y of them... It comes down to you having to use a specific hardware type (irrelevent of whether your current hardware supports HD). Just another point to M$ in the monopilisation of the computer industry.
I guess it could go 2 ways, 1) People move away from software that limits what they can and cannot do without due cause. 2) People will buy into it and some hardware manufacturers will be totally quids in, whereas others are left out to dry.
Im hoping for option 1, but I dont think that to be likely.
PS: The problem has already been addressed by a hacker who has successfully bypasssed this little hiccup, so if you were that way inclined, it shouldnt cause you a problem.
