I think the major difference is that with OpenBSD it's quite clear what it is, an OS so secure that it sacrifices comfort. That's not an option for most people using a Client and probably neither on the Server because those are usually deployed at work places where standardization is usually more important than sophistication. But I agree, it's not clear what NODE is for, although I get the impression it's a remake of 90s credit card sized "PDAs" (not sure if they ever had a real name).
