There are 64-bit apps out there. Almost any .NET 2.0 (or later) applications will be JIT compiled 64-bit at runtime. Examples of those are Paint .NET, my own Start++, and plenty of others.
There are lots of native code 64-bit apps too. SmartFTP has a 64-bit version. Zune 2.0 does as well. I'm sure there are plenty more as well.
Autodesk has been pretty big on 64-bit. 3dsmax and AutoCAD both have x64 versions.
Also, some games have been putting out 64-bit versions as well. HL2, for instance.
