Look at the date on that article. Two years old. I could find no mass market examples of this supposed "pisses all around" People are still clinging to old beliefs when it comes to this kind of thing.
Linux is NOT the lightweight it used to be. This is true of any OS that is trying to appeal to the masses. You have to give up speed for the usability that everyone wants. Finding a balance is what they aim to do however, and while I agree that Ubuntu CAN be faster in some regards, it's not faster overall than Windows, especially Windows 7.
Here are two examples, and they share the same viewpoints:
Ubuntu 10.10 Vs Windows 7 Vs Mac OS X 10.6 (Snow Leopard) | Expert Reviews
Further re-enforced by an article that while admittedly it's almost 2 years old, says pretty much the same thing:

You go right on believing that. That's what Apple users used to say about their OS of choice. The bottom line is that viruses and malware are targeted at the products that are used more than the others. Ubuntu/Mac would need scanners too if they were as popular and as widespread as Windows.
