I use NFS as a keystone of a pretty large multi-million data center application. I run it on a dedicated 100Gb network with 9k frames and it works fantastic. I'm pretty sure it is still use in many, many places because... it works!
I don't need to "remember NFS", NFS is a big part of my day!
On a smaller scale, I run multiple PC's in house diskless with NFS root; so easy to just create copies on the server and boot into them as needed, it's almost one image per bloated app these days (server also boots PC's into Windows using iSCSI/SCST and old DOS boxes from 386 onwards with etherboot/samba). Probably a bit biased due to doing a lot of hardware hacking where virtualisation solutions take so much more effect, but got to agree NFS (from V2 through V4) just works.
