NFS or Samba with Windows 7

[Linda]

I have to put a Windows 7 machine on my network. Has anyone had any 
experience with using its NFS client to connect to an Ubuntu server.  
Right now Samba seems to work fine for connecting the drives. Since I 
have to upgrade to professional that has the NFS client option I was 
wondering if anyone had experience with it versus just using Samba. 
Currently I use NFS with the other Linux machines and XP, but Samba with 
our lone Vista machine.
                  Thanks
