Laptop Shopping GuideSize, Weight, Portability vs. PerformanceThere are 4 major types of notebook computers: Ultra Portables: 4 lbs. or less, 0.5 inches or less thick, 12" inches or less display. Usually no internal CD, DVD or CDRW drive. They are pretty expensive and performance is limited. But it is THE choice for those who travels with the notebook computer a lot. Light Notebooks: 4-6 lbs, 1" or less thick, 12" - 14" display, 1 swappable internal optical drive. If you travel frequently but still want a notebook with decent features, this might be the choice for you. It has all standard slots, choice of ordinary CPUs, large hard drives, and a display easy to your eyes. Value Notebooks: 6-8 lbs, 1" or more thick, 14" or larger display, 2 internal drive bay. The cheapest notebooks are in this category. Good for those who would like a portable computer with the price of a desktop. Desktop Replacements: 7+ lbs, thick and heavy, 15-17" display, 2+ internal drive bay, deluxe CPU, memory options, multimedia connectors. These are the best of notebooks. They can basicly do everything a desktop computer can do, or even do it better. But due to its size and weight, it is not so portable. But if you would like a fast computer to use in a few different locations that are pretty close, this might be the choice for you. ScreenAll notebook computer's displays are LCDs. There are 2 major types of LCD. XGA and TFT. XGA is short for Extended Graphics Array, a high-resolution graphics standard introduced by IBM in 1990.
It allows monitors to be non-interlaced and provides more colors comparing with
older technologies. For size, of course, the larger, the better. But larger screens usually cost more and affect the portability. 14-15" should be enough for common notebook computer users. There is another factor you may see in display specifications - resolution. LCDs, unlike ordinary CRT monitors, has a native resolution, all other resolutions will look worse. for more LCD information, see our LCD monitor shopping guide. SXGA: A display with 1280 x 1024 pixel resolution. WXGA is not only refering to resolution, it means the display is wider and has a 16:10 aspect ratio which is good for DVD view.
