Long story short: of course you have to be careful when using technology. The issue with wireless is that so many people never even put a password on their network. First bad step. Second, there were issues with how secure the earlier wireless protocols were. These days though, if you password protect your network, keep a firewall on your computer, use secure connections and just generally dont' act like an idiot, i wouldn't worry about buying machine guns :-)
