The way Microsoft implemented 32-bit support in Windows 64 broke a lot of the legacy applications I help maintain (from an admin/support standpoint, not development standpoint) at work. Years after switching to 64-bit Windows, we still uncover subtle bugs that need to be patched in our configuration or by the vendor (if they still exist). If these applications were more mission-critical, we'd definitely want to stick with 32-bit Windows.
