Or you can have a protected computer-on-an-USB-stick that you can carry around when you visit unsecure locations, to avoid becoming infected from the host PCs that you use at public kiosks or hotels.

If you have to jointly author a spreadsheet with a colleague, what is the first thing that you do? Email it back and forth. This can be painful, particularly as you try to keep track of your partner's changes and hope the emails transit back and forth across the Internet.
