I appreciate the reply in the 64bit thread, although it's locked so I can't reply.
The lack of priority for 64bit systems amazes me. Almost every new server we build for clients is 64bit, and it's been that way for over a year. I think there has been a major underestimation of the size of the 64bit market, which I don't know how you do your research (please tell me its more than a poll & thread), but it's growing at a faster than moore's law pace.
Just think about the fact that it's a "Web 2.0" application that runs on only "Web 1.0" hardware.
