Weight

The travel weight specified must include the weight of power adapters and media bays but most manufacturers mention just the weight of the system and its batteries. Check out the models in the following three ranges:

Display resolution

Displays have another criterion which needs scrutiny before purchase. It is the display resolution- higher the resolution cleaner and crisper will be the image. Resolution is number of pixels across the width and height of screen. 1024 x 768 means 1024 pixels across the height and 768 pixels across the width. Pixels mean the individual dots that make up the picture.

In specifications the standard screen and widescreen is specified with abbreviations as XGA, SXGA, WXGA, WSXGA or WUXGA. The widescreen are fast becoming the rage because the reading space increases more with slight increase in size.

1024 x 768 Small displays 12.1 in. usually have this resolution XGA (1024 x 768), WXGA resolutions (1280 x 800). Larger screens too come with so low resolutions and they are cheap and ideal for budget computers.

1400 x 1050 Many large displays 12.1 and 15 inches come with this resolution like SXGA+ (1400 by 1050) and give very good picture quality.

1920 x 1200 Models with such resolution WUXGA (1920 x 1200) is ideal for making movies as there is more detail in the image and more work space on the display. However a negative factor associated with such high resolution is that the fonts tend to be smaller, difficult to read especially for people with poor eyesight. This factor is corrected by changing the font size in operating system but the correction can have unintended effects on other programs.
