I'd be careful accusing people of being uninformed and dishonest, especially when you make errors in your own post.
.dmg files are disk images. In the case you are discussing the disk image contains an .app package that is copied to the users (or more generally, the systems) Applications folder. A closer equivalent of the .deb file would be the .pkg file, which works in a similar manner as you describe.
As to whether 'Linux' is a usability nightmare or not I'd argue is purely subjective. It is disingenuous to suggest that there isn't a steeper learning curve, however slight and for whatever reason it exists.
We're talking about dishonesty in saying that "Linux is a usability nightmare" from an article about improving Windows' usability. I'm not talking about learning curve here! He cited 2 examples regarding Linux's usability that I don't think are relevant at all.
>The fact of the matter is that Linux is NOT a usability nightmare and it's dishonest to say that.
This is not a fact at all. It's a matter of opinion. The author of TFA is equally wrong in asserting that it is in the way that he did, but dishonest? No more than the dishonesty of claiming that it factually isn't.
