I've happily been using tmpfs on /tmp/ for probably ten years now, and
can list some more benefits:

 - It allow diskless setups like LTSP to work the same way the default
   installation in Debian work.  They use read-only NFS-mounted file
   systems and a writable tmpfs mounted on /tmp/.

 - It reduces the number of disk writes on a laptop, allowing it to
   spin down the disk a bit longer.
