Buying a New Computer - Part One

Laptop or Desktop?

Are ready to buy a new computer? Today’s column will cover the external computer hardware. Next week’s column will discuss processor speed, memory, and hard drive storage, and operating systems.


You need to make a major decision before you start shopping. Do you want a laptop or desktop computer? If you currently use a laptop, then you will probably want to replace it with another laptop. However, if you have always used a desktop computer, you might be surprised to learn that today’s laptops can compete quite effectively with desktop computers in both memory capacity and processing speed.

The major advantages of desktop computer are the larger screen and sturdy keyboard. The negative to them is the size, especially if you live in a confined space like many of us at Travelers Rest. Both my husband Eddie and I use laptop computer all year round. I use a 17” Macbook Pro, and Eddie recently traded a 17” Acer running Windows XP for a new Dell Studio 17” running Windows 7. We both like the ease of using a laptop and being able to take it with us wherever we go. At home in New York Eddie attaches a second, external LCD monitor to his laptop, giving him additonal screen space.

Whichever style of computer you chose, you need to decide on the screen size. Screen size is measured on the diagonal, and the most common laptop screens are 13”, 15”, and 17”,  although there are some laptops with 12”, 14”, 16” , and even 18” screens. My personal recommendation is that if you using a laptop as your primary computer, buy a 17” screen. If, on the other hand, you plan to do a lot of air travel, or the laptop is going to be a second computer, consider a one of the smaller sizes. If you are buying a desktop computer you have your choice of LCD monitor sizes, starting at 20” and going up to 30”. The typical desktop system comes with a 20” or 24” screen.

Regardless of whether you use a laptop or desktop, you need to be aware of screen resolution. Screen resolution refers to the number of horizontal and vertical pixels that make up the image on the screen. The higher the resolution, the more pixels can fit on the screen. Previously, the standard resolution was 800 pixels horizontal by 600 pixels vertical. Today you are more likely to see screen resolutions of 1024 x 768 or 1600 x 1200. Higher resolution monitors present an extremely clear image, but the image (including text) may be too small for comfortable viewing.

The only way to decide which monitor/computer is best for you is to try before you buy. Plan a window shopping excursion to a store with a large computer department. If you plan on buying a Windows PC, a good place to visit is the Best Buy in Wesley Chapel. Only eighteen miles down I-75, the store has wide variety of computers on display. If you are considering a Macintosh, plan to visit one of the Apple stores either in Tampa, at the International Plaza, or in Brandon at the Brandon Town Center.

Take your time looking at the screens to see which size and resolution works for you. While you are previewing monitors, take some time to get the feel of the different keyboards. If you are planning to buy a laptop, try out the touch pad as well. Most laptop feature a touchpad, which works by dragging a finger across the pad, in place of a mouse. However, both a USB or wireless mouse can be used with laptops.

Write down the names of the computers you like best and in next week’s OnMouseClick column, I will discuss processor speed, memory, hard drive capacities, and operating systems.
