I like the way pg often uses a computer without internet. In fact, after posting this comment, I'm going to shut down this computer's net access for a bit so I can focus.
I read years ago about Jerry Pournelle having a separate computer on the upper level of his home with no internet connection at all, for the purpose of focusing on writing. I thought that was a neat idea, and tried it myself, but eventually started sneaking a wireless laptop with me, and before much longer gave up on it entirely.
It's weird. For years, I really did use computers with no network access whatsoever, and then with some basic telephone-line connections that were usually off, and now with wifi/broadband pretty ubiquitous, it seems unthinkable to get off the network. I feel like something is very wrong here, but... ooh, I just got an email; it must be time again to check to see if I've sold any more albums at CDBaby.com ...
My home is completely without external connections, except for a cell phone. To waste time online I have to go through quite an effort. Apparently, I've succeeded.
