The DRM in the Intel Mac isn't what it's made out to be. The only thing it's doing so far is checking that Rosetta is running code on the correct machine. The Tiger for Intel thing will run on any PC, but Rosetta won't emulate PPC code on just any machine. For all I know, it could be left-over code from the company that originally made Rosetta (not Apple).
And running OS X on an eMachines/Dell/crap o' the month PC would not seem right.
