Man! That article is spot on. I just bought an iPad last night with Quick Office as I will be traveling for two weeks and want to be able to communicate as I won’t be staying in motels. Also wary of public WiFi. My previous laptop was a 10-year old heavy Dell clunker so this will replace it when traveling and in the field.
I wrote a proxy.pac file and pointed my Firefox to use it all the time.
I also wrote an Expect script to create an encrypted SSh tunnel back to my home network.
This combination allows me to surf the net anywhere without fear of snooping.
