The biggest advantage is from a glance being able to:-

1) See what systems has what software installed
2) See which systems need critical updates applied.
3) The ability to automatically update software/rollout software onto a 
number of machines from a central location.
4) See which systems have not checked in for a given time and notify the 
user to connect them to the network to receive new updates (e.g. Laptop 
5) And probably the biggest reason, is that it links in with the errate 
database so you immediate visability of what systems are affected by 
what vunerability.

Whilst I would agree with the that much of this could be done though 
cron scripts, the RHN and (less central ways such as) YUM is that they 
both get though Firewalls quite easily.

The main thing I hate about RHN (despite up2date's GUI buggyness) is 
that it is red hat who control it.  Even there highest level product 
(Satallite version) does not give the adaptabily the comes from most 
other open-source and freely available solutions.
