Traveling with a laptop computer presents a set of practical challenges that aren't all related to operating the computer. If you travel by air, remember to prepare the computer and the related materials for a security check at each airport, and do whatever you can to avoid attracting attention to yourself or your computer to prevent theft.
While you're away from home, you may want to find a way to connect your computer to the Internet, or to print one or more files or documents. There are plenty of public Internet access points, commercial copy shops, and business centers that can provide the services you need.
