"Sub Question" of and inspired by Marina's question about the pros and cons of new technologies in our lives.

Some answers in this question mentioned that being accessible 24/7 is a definite con of all this new technology. While it’s true, you’re not really accessible if you don’t want to be. One doesn’t have to check email or keep the cell phone on all the time. So do you feel that the technology makes you accessible, or is it really that the technology forces you to feel obligated to be accessible?
