I was working at a very large bicycle shop in Toronto, Canada when N600 came out and also when the 105 groupset came out. The N in the 600 stood for New to differentiate it from the earlier 600 EX stuff. The 105 stuff was always referred to as Shimano 105 or simply 105.
There are so many variants of 105 now since it was first introduced that it gets confusing when someone says they have 105 parts.
