Fat32 is a very poor filesystem and Nokia chose it for the n900's MyDocs directory so Windows users could view their files if the n900 is plugged into a Windows PC via USB cable. Those of us who use the n900 on Linux machines (or use SSH/SFTP to access files) have the flexibility to use a better filesystem.
