If you must buy a computer or laptop, be sure to get Dell's Complete Care Warranty option because it covers most accidental damage such as drops and spills.  This covers all the bases since you never know if your computer stop working because it's defective or it's your fault.  The best option is to pay a little extra so you don't have to worry or have the hassle of proving it's not your fault and that you were shipped a defective computer.  This type of warranty is best for the cost/benefit for a 3 or 4 yr package since by then, most likely something may happen to your computer and you may need a replacement.
