I still don't understand why that idiotic channel numbering came to be.

Around here some people have learned that if a landlord can advertise "wired for ethernet" or something like that, it 
makes the property more desirable, though I'm not sure if that translates into higher rents.

At some large NYC apartment buildings pre-wiring for data is considered a big plus.

The claimed data rates are impossible to achieve, even in a lab. I don't know how they get away with that, it certainly 
seems much more egregious than using industry-standard numbers for hard drive capacity.

It took me only seconds to find this statement about a product:

"Through your home WiFi connection, you can enjoy the entire shared digital media library of your home PC in your living 
room, not just in your office".

If your "shared digital media" includes HD video, this is a misleading statement at the least, and just about every 
product says something similar.
