WiFi - one computer at a time - common?

Be aware that these are public Wifi and shared by everyone so not a good idea to use more than necessary and not to use for banking or credit charge transactions. We see the passwords posted at the office front desk, sometimes in the window, and it is never changed from one year to the next.

For a mifi device the best plan is with millenicom.com where there is no contract and the rates are half that of Verizon though you use the Verizon network.
