During my typical day, 0 people attempt to contact me by phone, and I spend almost all the time bathed in wireless connectivity. I am out of touch for a total of 40 minutes when I am walking to or from work, and perhaps another half hour when I am off campus for dinner.<p>I did have an incident very recently when I traveled to a part of campus I don't normally frequent and couldn't find an open access point so that I could request entry to the building. I lost at most half an hour finding an access point nearby, and in the future I can walk directly to the AP if the need arises, so it was a one-time cost.<p>There is also significant one-time savings from an iPod vs. a smartphone, to the tune of $200-$300.
