First: I know this topic is slightly "sub" related to PLi and hope it's not instantly removed by the moderators, but if so I'll understand 
I had a discussion about the use of scheduled reboot and would like to know about the pros and contras or the sense or nonsense. To make a start...
PRO's
Scheduled reboot is often used to give the routers a little clearing now and then to keep its performance at its peak.
Contra
I find it's really unnecessary though, there should never be any reason you need to reboot every day, or ever for that matter, unless you make substantial config changes that require it or a firmware update
