Hitting the road with your computer opens the doors to a whole world of potential security problems, both physical and software-based, but don't worry. They're all manageable. Remember, the weakest link in your security will usually be you—as long as you don't put yourself, your computer, or its data at undue risk, you should be just fine even if you have to work from a library or a coffee shop, or connect to whatever Wi-Fi you find to get some work done.
They’re everywhere: in cars, shopping malls, and restaurants, even at family and professional sporting events. They are so common place these days, I'm not sure I know anyone who doesn't own one...the "attached at the hip" CELL PHONE!! Have you noticed, though, how often a wireless phone isn’t being used to actually talk to another person.
Unless you're a hermit, you are out and about every day, sometimes several time a day. And each time you venture outdoors, whether it's to a meeting, the grocery store, a concert, sporting event, or on vacation, it's an occasion for something to happen to your mobile phone or the information in it.
