Nice to play with maybe. However since only Itanium and the AMD64 are viable Windows 64Bit systems and out of 60,000+ Servers and Workstations we only have like mabye 3 64Bit systems I would have to say that beyond "interest" currently do not have a "need" for it. Of course as with anything, as this ramps up and more and more applications become available the more systems that will start showing up and running 64Bit.
