We all can't still live in the days where our infrastructure is running on Server 2000 with SQL 2000. Wake up, everything is 64bit now and will be that way for sometime until 128-bit computing comes out. It's like IPv6. Everyone wants to complain that they are being forced to move to something when it has been around for almost 10 years now.
Server 2003 64-bit has been out since 2005. If you are too lazy to deploy 64-bit servers or don't have the hardware then it is time to get into the 21st centruy and upgrade those 10/100 switches, Windows XP machines, and 32-bit servers to 64-bit. The next client release of Windows is 64 bit only, and the current release of Server 2008 R2 is 64-bit only.
