Possibly the single most annoying difference is that Cisco uses the 
command "ip router isis <tag>" to activate isis on an interface, vs just 
"ip ospf" with no "router". Now imagine you're tired and trying to take 
isis off an interface, and instead of typing "no ip router isis" you 
accidentally type "no router isis", and guess what happens. :)
