Читать книгу Laptops For Dummies - Dan Gookin - Страница 36

Throughout laptop history, five key items have been vital to the laptop-choosing decision:

Weight: Nearly all laptops weigh between 2 and 7 pounds. The heavier laptops, the notebooks, have more features, such as a larger display or a numeric keypad next to the keyboard. The lighter models, the tablet PCs and subnotebooks, don’t necessarily have fewer features; they might actually have more lightweight or advanced features, which makes them more expensive.

Size: Most laptops are thinner than an inch. Tablet PCs are the thinnest. Subnotebooks are the smallest.

Display: Recently, manufacturers have discovered that people love the larger screen on a laptop — even though the larger display adds to the laptop's size and weight (and consumes more battery power). For a laptop being used at one location and only rarely going on the road, a huge display is wonderful. If you want portability, though, and a longer battery life, consider a smaller display.

Touchscreen display: If the laptop advertises itself as a tablet PC, or a convertible notebook, it has a touchscreen display. You can use your finger to manipulate the touchscreen. If the laptop comes with a digital stylus or pen, all the better.

Battery life: Despite their manufacturers’ claims, most laptops run anywhere from three to five hours unplugged. Subnotebooks and tablet PCs hold the record, with many of them lasting as long as ten hours. Regardless, it’s possible and necessary to manage the laptop’s power; see Chapters 10 and 23.

  Stuff that's important to the overall weight of the laptop — the power brick and cord, keyboard cover, extra batteries, portable storage, and other gizmos — aren’t included in the basic tonnage calculation. Keep these items in mind when weight is important to you.

 Convertible laptops, especially those with a twisting-folding lid, are thicker than standard laptops because of the extra circuitry required for their touchscreen displays. See Chapter 7.

  If you desire both a large display and portability, consider getting an external monitor for your laptop. This way, you can enjoy the big, roomy screen when the laptop is at your workstation and still have the portability you need when taking the laptop on the road.
