Tech is only different if you play by the game wherein anything that doesn't abuse a computer's stats is not worth toying with.
I'm guilty of playing this game along with everybody else, but at some point we'll realize that we don't need all of what we've got, and we'll start being satisfied with it. Hell, I can see myself sticking with the laptop I've got right now for a decade.
If you want to separate yourself from the world, then you could still use typewriters. Typewriters can't receive e-mail. Similarly, a Pentium can't run modern Web applications at a reasonable speed. A ten-year-old cellphone won't have a camera and all the associated applications of that. You can stay with old hardware -- but at the cost of eventually giving up access to contemporary applications.
