Determine what type of software you will use on your computer.

This will help you determine how much memory, storage, speed and other requirements you will need.  Certain software products can only run on Macintosh while others run on the PC.  Also some computers are bundled with software.  At the very minimum you will want a word processor and browser to access the WWW.

Do some research before purchasing a computer.

Ask other people what type of computer they purchased and why.  Also, visit websites or read reviews in magazines.  When doing your research consider the following:
Speed of the processor
Size and types of memory (RAM) and storage (hard disk, floppy disk, CD-ROM, DVD-ROM, Zip® drive)
Input/output devices included with the system (e.g., mouse, keyboard, monitor, printer, sound card, video card)
Communications devices included with the system (modem, network interface card (NIC))
Any software included with the system
Overall system cost

Look for free software.

Many companies offer free software with the systems.  Some even let you choose the software you want.  Just remember that the software only has value if you would have purchased it had it not come with your system.

Review your purchasing options: buying from school, a local computer dealer, a local large retail store, or mail order by phone or World Wide Web.

Each option has its advantage.  Schools may offer discounts through and agreement with the manufacturer.  Local dealers and retailers will offer hands-on support.  Mail-order purchases will probably offer the lowest prices but less personal service.

If you’re buying a used computer, stick with name brands.

Although name brands cost more, these systems will most likely have longer more comprehensive warranties.

Use a worksheet to compare computer systems, services and other considerations.

Use a separate sheet of paper or a spreadsheet to compare each vendors computer system.  Most companies advertise a complete system but beware some companies list prices that include only some of the components.

Be aware of hidden costs.

Before purchasing a computer, consider any additional costs associated with buying a computer, such as an additional telephone line, computer furniture, disks, paper and computer training classes.  Depending on where you buy your computer, the seller may include some of these things in the system price.

Consider more than just the price.

The lowest priced system may net be the best buy.  Consider such things such as: how long has the vendor been in business, the vendor’s regard for quality, and the vendor’s reputation for support.  Also consider if you will be upgrading your system often, leasing may be an option.  If you are replacing an older system, ask the vendor if they are willing to buy it.  No matter what type of buyer you are, insist on a 30-day, no questions-asked return policy return on your computer system.

Buy a system compatible with the ones you use elsewhere.

Having a computer compatible with ones used at school or at work will allow you to transfer files and spend time at home on work – or school-related projects.

Consider purchasing and onsite service agreement.

Most onsite service agreements state that a technician will come to your home, work, or school within 24 hrs.

Use a credit card to purchase your system.

Many credit cards now offer purchase protection and extended warranty benefits that cover you in case of loss of or damage to purchased goods.  If you are dissatisfied with the product and are unable to reach an agreement with the seller, paying by credit card gives you certain rights regarding withholding payment until the dispute is resolved.

Avoid buying the smallest system available.

Computer technology changes rapidly, meaning a computer system that seems powerful enough today may not serve your computer needs in a few years.  Plan to buy a system that will last you for two or three years.
