But x86 is not merely 64-bit computing, it also adds more registers, more efficient encryption/decryption, and hardware NX capabilities. Other than that you're right, not very useful.
Yes, of course x86 is that, but that's part of the x86 platform, not something on which Microsoft is "behind the curve."
I'm saying Windows NT for the Alpha would not be very useful for your average desktop user.
Agreed. The 64-bit capabilities in Tiger--and for that matter, when the x86 version of Windows is released--are not very useful for the average desktop user, either, at this point. All I'm saying is, Microsoft has been supporting 64-bit environments for some time. Saying they are behind Apple when it comes to 64-bit OSes is just not accurate.
