Any reason not to disable the Windows pagefile given enough physical RAM?
I believe that there is enough of memory for everything used at the moment to be stored and that nothing needs to be paged to disk. Is this true?

Unless you are severely limited on disk space, there's really no good reason to run Windows without a pagefile. Its designed to use one, and many performance issues are caused by users thinking they are smarter than the OS's built in routines (such as the CPU scheduler, memory manager, etc).
If you are using a 64 bit version of Windows, I wouldn't disable it since the memory limit is way over 4GB. From Pushing the Limits of Windows: Physical Memory:
64-bit Windows client SKUs support different amounts of memory as a SKU-differentiating feature, with the low end being 512MB for Windows XP Starter to 128GB for Vista Ultimate and 192GB for Windows 7 Ultimate.
What you can do is lower the initial size of the page file (for example to 1 GB), and left the maximun size as the recommended size, so Windows can use it if needed.
Windows has always been using much of useless pagefile memory. Even if you disable paging it will not actually stop doing that.
Be aware that you will need pagefile memory for doing hibernate.
