If you haven't heard about the new Firefox extension called Firesheep that Eric Butler built then be very afraid to use public wifi. Read my blog post about Protecting yourself from Firesheep.
The short version is to not try and kill Firesheep, but rather just avoid the issue altogether. How is this best done? By using Sprint Mobile Broadband or a Verizon Mobile HotSpot this allows you to completely avoid those so called free Wifi hotspots. "Free" suddenly isn't so free when you are risking your computer getting taken over by anyone who downloads a free extension off of the Internet. Is this a shameless plug for the technology we sell? Of course it is! But that doesn't change the fact that open access WiFi is scary stuff indeed.
