    Always-on broadband connections. (IP address changes infrequently.)

  2. Safety of online shopping.

    Things I've bought online: truck, truck loan, mortgage, TV, DVD player, computer equipment, books.

    I did once receive an e-mail saying an online merchant had been hacked and it was possible the hacker had my credit card info. What did I do?
