Of course :-). But I don't think many of us believe that MMX was
designed for a mulitasking environment :-). MMX's main use appears
to be targetted at desktop stuff. And the MS-Intel alliance takes
every opportunity to force upgrades on their customers :-(. It looks
more like a strategic decision got made by the wrong people somewhere
along the line :-).
