Whitewash---The issue is NOT whether the mobile market will use TPMs/Trustzone. I don't dispute that. Therefore I'm not quite sure how Nokia is relevant to the Xbox question.
The issues revolving around XBOX relate to the question of whether XBOX-360 will allow the downloading of PREMIUM CONTENT without HARDWARE AUTHENTICATION. Because without hardware authentication XBOX is going to be hacked to death! And I might add that XBOX has always used hardware security; but the security hardware was easily modified by hackers because there was no way for MS to authenticate the hardware.
So if the XBOX really does have a TPM embedded inside, who else is in a position to manage/provide both the Interoperablity and Hardware Authentication outside of WAVE?
