I tend to agree. You know, there are times when my computer *doesn't* have a network connection. My ebook reader doesn't really need one - once I have that puppy loaded with a library from Gutenberg, Baen, Webscriptions, and a dozen other ebooks sources, what do I need the web for? To look up some obscure reference in a book? Nice, but I read a lot of books for a long time, before that ever became commonplace. I learned to get the *CONTEXT* of the idea, and work it out from there.
Seriously, just this evening, I was having random inability to get to huge chunks of the Internet - at one point, even Google wouldn't come up for about 30 minutes. If I have nothing local - I have a paperweight on my desktop if my network goes down.
And honestly, the best way to keep a computer virus-free? Don't connect it to the Net!
