Most users are going to have a Mac and a Windows machine, SMB makes far more sense. You're going to see NFS in enterprise situations and Apple does not really aim there target there.

Not only that but nfsv4 has its own issues in regards to userid/gid mapping.

Setting that up with kerberos is... not fun (speaking from the solaris/linux/aix side of things).

Not that smb would be better for most unixes mind you, just that nfsv4 is its own version of hell in some ways.
