Care of your laptop is important be it a new laptop or a bargain Refurbished Laptop computer. A case serves two basic functions, protection and ease of carrying. In both categories there are many options to choose from and the costs for a good case vary greatly. It is a good idea to consider several cases for different uses. For many years I traveled with a laptop case that carried the laptop and work papers, and was heavy to the point of causing fatigue when carrying both a laptop bag and carry on luggage. The laptop case was so large that it became a problem fitting the case under the airplane seat ahead of me. Because a laptop case can get pretty beat up when traveling I recommend cheap laptop bags in addition to a second or third bag for other than travel uses. Keep in mind that if you take care of your laptop even if was a laptop under $100 that you picked up for a cheap price it will reward you with many years of reliable use.
