Use word-processing software to document what your needs are as a computer user and your justification for selecting either a desktop or some form of a portable computer. Find a Web site that allows you to order and customize a computer and select those options that will best meet your needs in a cost-effective manner. Assume that you have a budget of $850. Enter the computer specifications you selected along with the associated costs from the Web site into an Excel spreadsheet. Insert that spreadsheet into the document defining your needs.
