After "talking" with some of my road warrior friends/relatives, I am told that (indeed) wireless security is a concern when traveling.
So now what, concerning my intended purchase of a netbook?
One friend said be sure to have security software, which I would have had anyway. And to be really cautious about doing any transactions requiring a credit card. However, I would want to sign into various things (including this blog, just maybe) and - obviously I don't want to have my passwords stolen.
Another (who is a professional in the internet field) recommended getting a network card for a nationwide wireless network and paying for prepaid service. That might be an idea if I could figure out how to install a card. I checked one such service out and I could actually buy netbooks from them with the card installed. That may be an idea, if I can get exactly what I want.
