I'm not sure that with many outside security that reliable equates with 
security in mind.  More often it equates with uptime, or time between 
reboots due to system hangs.  Point being, one can not simply ask how 
reliable is it, without adding more to the context of the questing 
evaluation.  "One man's garbage being another's treasure"...
