Sorry to be off topic but I just read through that thread, which I started. First, I am amazed at what a great online community this is as there are so many knowledgeable people who are willing to help. Second I realize how bad my dealer was who sold me the C15. Had no clue. Since then, thanks to this site, I have a real dealer who knows all about M and is willing to go the extra mile to help a customer out.

A bit more on topic. Since those early days I have installed managed business class switches on my LAN in an abundance of caution. They have much more processing power and have a variety of other useful, but not absolutely necessary, features.
