Travel laptops require more consideration on top of the usual factors involved in buying a laptop, such as performance, price and warranty. Getting a system that is light is critical. With widescreen models becoming more popular, whilst great for viewing, it just adds weight to the system. If you are not into watching movies or complex graphics, a smaller screen should be fine.

While the price of laptops compared to desktops has shrunk recently, you will still pay slightly more for a laptop. With laptops reasonably difficult to expand or upgrade, its a good idea to add more memory or get a bigger hard drive at the time of purchase. Your system should have at least two USB 2.0 ports, as this will be the main way of connecting to external devices.

If you are a frequent traveler and want to use your laptop while flying, there are some other design issues you might want to consider. Widescreen laptops can be a hassle if you are in the coach section, as there is hardly enough room to open the machine. A system with external controls for volume and Wi-Fi can also be good, to avoid annoying other passengers or interfering with the aircrafts navigational system. For really long flights, a second battery is probably the most cost effective way of keeping your system powered up.

As laptops are more likely to be damaged or stolen while on the road, it is a good idea to have a backup plan. Do a regular backup so if something bad does happen, you dont lose too much data. The easiest way to do this is to buy a laptop with a built in DVD burner. One DVD disc should be more than enough to store your work data. You could also use a CD burner, but you would probably need to carry multiple discs. If you only have a small amount of files you need to backup, a USB flash drive would also do the job.

Laptops that are on the road regularly are more likely to break down. So invest in a good quality carry case to limit any potential damage in transit, and always keep your backups up to date.

Most warranties these days are only twelve months, so if there is a extended warranty available, it may be worth taking up if you are constantly on the road.
