Cost of ownershipMaintenance

Replacement cycle

The cost of initially purchasing the equipment is often the biggest cost involved in the selection of a computing platform. Not only must the main computing devices be purchased, but the appropriate software and peripherals must be purchased as well. For a large number of devices, the cost of software licenses for each device can often be expensive. Some computing platforms have the advantage of being bundled with a lot of included essential software. For example, some computers are sold with productivity or entertainment software preloaded. Other platforms boast the use of free online apps and services, making most software purchases unnecessary. This can lower the initial cost of purchase substantially.

The cost of ownership is often not considered as carefully as it should be. Any computing platform will require some regular maintenance of both the software and hardware. For example, on the software side, many antivirus programs require a yearly subscription, adding to the cost of ownership.

On the hardware side, some laptops have batteries that need to be replaced every year or two because of the batteries’ short service life, Furthermore, depending on the hardware build quality and software support provided, the useful service life of a computing device can vary widely. Some computing platforms require complete replacement of devices every three years, while other platforms can last five or more years. Trade magazines and organizations like CNET.com, PCMag.com, and MacWorld.com offer regular reviews and comparisons of current products to help estimate the cost of ownership.

The cost of purchasing and owning computing devices from various platforms varies widely. Bigger and faster does not always mean more expensive. Desktop computer prices can range from as low as a couple hundred dollars to several thousands of dollars. Similarly, laptop computer prices can range from as low as a couple hundred dollars to several thousands of dollars. Mobile computing devices can range from as low as a couple hundred dollars to almost a thousand dollars. Once again, using resources from online trade organizations can help with performance and cost estimates.

DESKTOPS, LAPTOPS, AND TABLETS

Computing platforms currently available span the full gamut of (1) physical functionality, (2) computational functionality, and (3) cost combinations. For example, there are large inexpensive desktop computers with lots of computing power, tiny expensive mobile devices with limited computational functionality, as well as large moderately priced mobile devices with lots of computational functionality.

To help structure the discussion of the various platform strengths and weaknesses, three broad device categories on the physical form spectrum will be considered in order: (1) desktops, (2) laptops, and (3) tablets. These three tend to provide the most computational functionality for tasks that may be performed in a school setting. The strengths and weakness of these three are also discussed as they relate to performing common schools tasks such as:

Conducting web research

Communicating with email and social media

Writing and printing papers

Creating and sharing presentations

Facilitating interactive classroom activities

Facilitating activities outside of a dedicated computer lab

Working with graphics and multimedia
