Exchange Server 2007 Installation Marathon Day 2 - Why does it only support 64bit OS?

Basically 4GB memory limitation is the bottleneck of 32bit OS. When the hardware become cheaper and cheaper, also users with faster network speed (are you still using dial-up internet?) need faster response from server side.
So in an enterprise environment with thousands clients, 4 GB RAM is much less than neccesary for spooling, scanning virus and filtering spams.
