Most people who purchase laptops do so because they want a portable computer. That's what they are designed for: portability. However, it is not wise to just tuck your laptop under your arm and carry it with you wherever you go. For one thing, it is too exposed to the elements and can easily be dropped if someone bumps into you. For another, you usually need to take at least a few accessories with you. When you buy a laptop, buy a laptop carrying case that is designed for your laptop and the accessories you need.
Today's laptops have much longer battery lives than older models, but they don't last forever and certainly can't take you through a long working day. Unless you're just stepping out for a coffee, you need to take your charger cable with you. Any laptop carrying case will have a separate area for this, even if it has a bulky AC adaptor.
Most laptop users like to use a mouse instead of or in conjunction with their touchpad. Your laptop carrying case should have enough room inside for this as well. So far, with only a laptop, a cable and a mouse inside the case, just about any case will do, right?
In fact, if your case is going to be carrying any accessories at all, you really should take a good look at how well it is going to secure those laptop accessories. If you have ever owned a cheap nylon case, you'll know that you will often find that your computer, mouse and power cord end up jostling around in the case. This can't be good for your laptop or your accessories in the long run.
The situation gets even more critical if you need to pack a USB cable, a memory stick, some CDs or DVDs and/or any of the other many accessories we typically need for our laptops. Carrying all of these items in a cheap laptop carrying case is little better than just tossing them into a bag. The case doesn't protect the items from outside impact and doesn't protect them from internal impact and abrasion.
If you're going to buy a case for your laptop, there is no reason not to buy a good one. The best cases are aluminum laptop carrying cases. They protect your computer from outside impact and are designed to keep all of your accessories held securely in their various compartments.
Open up an aluminum laptop briefcase and you will see that everything you packed inside it remains where you placed it. Whether you just carry the basic accessories with you or carry everything, there is a place for everything in your aluminum laptop carrying case and everything remains in its place. You won't settle for less than the best laptop: neither should you settle for less than the best case for your laptop.
