I'm about to take the plunge and build a PC, and it will probably be 64-bit, which will use 64-bit VISTA, I suppose, since Windows 7 isn't out yet.
I'm a Visual Studio 2008 developer; will I need new versions of the software? I run the 32-bit versions on XP right now and deploy to a 64-bit Windows 2003 server that runs IIS in 32-bit mode.
