disadvantages of linux cluster

Disadvantage of such a distributed environment would be administrative and 
maintaince cost as you said, apart from communication interconnect. 
(assuming that we are comparing PC-cluster with SGI-multiproc machine)

It is extremely stable (Linux based distributed environments).
Absolutely, it is designed to be work in high load. (mentioning multi-user
is rather trivial due to fact that very good solutions on load-balancing) 
How experimental a cluster is depends on owner and his/her implementation?
One should optimize needs versus availability. Pros and cons of
interconnect selection. One should consider power of GNU/Linux
