So, a few years ago I was really impressed with how much 
faster the dec alpas were. Now it seems that the 32bit wafer 
technology has caught up and the difference is now only 
maybe 10%. It would seem to me that this is not enough of a 
difference to drive a switch to 64bit arch, other than the 
previously stated fact that there will be no more 32bit 
chips from the big two after this year. The software writers 
  have no motivation to convert to 64 bit rapidly, they will 
eventually but not as a need but just as a function of the 
experience of the programmers that succeed those coding now.
