Funny, my view is the exact opposite. I first used 64 bit on a Dec Alpha 
in about 1993. I have been wondering ever since why anybody would want 
to cling to 32 bit. Recently I have been puzzled as to why anybody would 
want to run a 32 bit opsys on 64 bit hardware. I think they just sense a 
lack of commitment from Microsoft. Incidentally, I heard that Microsoft 
had a 64 bit version of NT (an early one 3.1 or 3.5) for the Dec Alpha 
but never released it. They released a 32 bit version for the Alpha - so 
everybody ran Tru64 unix instead. The attraction of 64 bit is address 
space more than large physical memory. If you are mapping large files 
the address space issue is significant. A windows 32 bit application can 
get about 1.5GB of usable address space in an application and it is not 
enough. I had better declare my bias; I implement an APL interpreter. A 
significant number of my users are bouncing off address space 
restrictions and are being held back because their users are constrained 
to use 32 bit windows as a platform.
