How many of the people complaining here are the same ones that complain when their employers limit their access to the internet?
I work for the government and the computers are locked down so tight that it becomes impossible to work efficiently (i.e. thumb drives, preventing us from getting on required govt web sites, etc...). I especially liked when they blocked the website to complete the mandatory computer security training.
Any time you use an ATM that info is going over the internet. Every Company you do business with likely puts your information on a server. It is encrypted as I am sure that CBP info is to their servers.
Yes, there is risk at plugging any computer into the internet. We either must accept that risk as a part of doing business today, or the internet becomes a vast repository of pirated music and porn and we go back to paper records for everything.
