Screens aren't likely to get much larger than these, because the size of the laptop would become unwieldy, and we'd be back to the old days. As it is, the Dell's case is 13 inches wide and weighs about 8 pounds. The PowerBook is a half-inch wider but lighter by 3 pounds. It also lacks the Inspiron's two compartments that can exchange DVD, CD burner, floppy and other drives. The pixels are the little dots that combine to make up words and pictures.
XGA resolution is probably the most common setting on today's desktops and many laptops.
There are laptops with resolutions of 1,280 by 1,024 and 1,400 by 1,050, but the UXGA screen breaks new ground. The numbers are just tech specs, but you need just one look to see the difference the higher resolution makes. Twelve-point text in a word processor is tiny but exquisitely sharp. It's almost like viewing text on a printed page, which means extended work sessions are easier on the eyes. Two pages of text fit comfortably side by side, although the lettering isn't as sharp and distinct as the Inspiron's.
