Computers and security
Obey the new security restrictions
Some people (including me) do find it very difficult to travel without their own computer. These people need to make sure that they have a small robust laptop which has a reasonable battery life and for which the necessary accessories (power adapter etc.) are also light and easy to carry. Additional batteries may be required if you are going to be away from mains electricity for a period of time so do plan in advance.
Portable computing has come on in leaps and bounds. Battery life, size and weight, which have for so long been the bane of the business traveller, are now less of an issue with the current choice of ultra-portable laptops. These come equipped with a 12-inch screen or smaller, extended battery life or additional battery, external optical drive, built in 3G and wireless networking, and a weight of less than 2kg.
When travelling, never use a lap-top carrying case but place your laptop in a briefcase (or like me in a large ladies handbag) so that you aren't advertising what you are carrying. Also remember when packing that some airports (especially in the US) require you to take out and turn on your laptop when going through security so don’t pack it carefully in the middle of your carry-on.
Don't leave your lap-top unattended in a hotel room, office or car without locking it securely to something solid (the handle of a filing cabinet, base of a bed or spare tire in the trunk of a car. Use privacy filters to prevent shoulder surfers and other wandering eyes from stealing user IDs and passwords and be aware of your surroundings.
Carry essential data on a memory stick in your pocket in case anything happens and please ensure that all data is backed up before you leave home.
