Soft NFS mounting writable file systems is a bad idea as few programs handle
failed writes gracefully (esp. when the same write has previously
succeeded).  Your system won't hang but you will likely end up with corrupt
data instead.

Hard mounting with the intr option will allow you to kill (or interrupt) hung
processes giving you some control over the problem.

The infinite timeout in NFS was a conscious design decision because it allows
file servers to crash and be rebooted w/o any (long term) affect on the
client.  IOW, once the server comes back, you just continue on with your work
as if nothing happened.  There are other ways to implement this but they
require more complex clients and servers.  Keep in mind that NFS was invented
when UNIX servers with 4MB RAM were commonplace.

Like most software, NFS works well when used properly.  That includes sharing
of user credentials with NIS or something else as mentioned in a previous
post and carefully crafted automount maps.  I have worked with some excellent
NFS setups and with some poor ones.  Well designed setups are a pleasure to
work with.
