We call them "road warriors." Or maybe just "huge nerd" would suffice. Some are students, others dyed-in-the-wool geeks. Whatever, it doesn't matter. The bottom line is that all of us have seen this particularly non-elusive breed of tech aficionado, usually sitting at a Borders, Barnes & Noble, or especially, a Panera Bread cafe. We're breeding like rabbits.

Virtually all of these establishments either condone or even encourage people to pull up a chair, stay awhile, fire up your laptop or phone, and take advantage of the Wi-Fi hotspot. Panera Bread even encourages patrons to make their restaurant their meeting place, and they offer free Wi-Fi access, too.
