Narrow-minded criticism of a country, from posters who are ashamed enough of their own country to not mention it in their profile, is another thing I dislike about some posters.
I am not referring to you, sodelicious.
Frankly, I find his opinion quite insulting. If I based my judment on, say, the whole USA and its inhabitants on my experience of the what people thought in say, Arkansas 40 years ago, I would rightfully be called names by US posters reading such statement from my part.

I live in Vancouver where the border crossings to US can amount to mucho hours in a lineup. I have family in Seattle so like to go there a few times a month. The nexus pass lets me zoom right through in minutes. I love it.
Yes, I had concerns about my privacy but considering that I use credit cards and post on the internet and reveal myself in a million ways everyday I figured the US having my fingerprints and retina scan was pretty much moot. And it's my understanding that the eyeball scan thing is going to become the new normal for international travel anyway.
A Supplementary Question.
IF I get this Nexus Card, which I probably will, when I fly from San Jose, Costa Rica to Miami, is there a Nexus queue so I don't have to suffer through US Immigration at the Miami Airport which I recall is awful? I realize this would be the eyeball scan card.

In theory, no. There is no actual Nexus queue for anything other than Canada/US crossings
However, you can sometimes get away with going through the crew lineup with your Nexus card, even though it's not supposed to be for that. Hit and miss, and if you miss then you hit the back of the regular line.
The machines have improved quite allot recently and I havent had a failure in about 8 months. Loudly saying "damn machine isnt working usually will get you access to the crew line, but if you are going through YYZ go to the machines on the left as that is where the crew lines are.
OK - I submitted the application on-line about a week ago. How long will I have to wait for my interview? I guess for the full deal - eyeball scan and all - I have to go to YVR, at least that is what my friend said, and that's fine because I'm only a short drive (or much cheaper bus ride) away.

you'll get a conditional acceptance within two weeks and with that they will ask you to book an interview time at whatever choice of locations is available to you locally. here in the vancouver the earliest available appointment was 3 month from the date I received the conditional acceptance. When you go do the interview you get the card on the spot.
