Sony Electronics' full-sized, 7.3-pound Vaio K series laptops sport a new silver casing and two-tone chassis. What's on the inside is new, too, with 802.11b/g wireless networking and 15.0-inch screens with Sony's XBrite technology backed by ATI Radeon IGP 345M graphics. XBrite provides high contrast, crisp graphics, and vivid color when editing digital video for storage on the built-in DVD±RW drive (or DVD-ROM/CD-RW drive on the $1,400 Vaio K13 model).

The K13 has a 2.8GHz (533MHz bus) Pentium 4 processor, 512MB of memory, and a 40GB hard disk. Stepping up to the K15 ($1,700) brings not only the DVD burner with Sony's Click To DVD software, but a 60GB hard disk, while the $1,900 Vaio K17 flaunts a 3.06GHz Pentium 4 chip and 80GB drive. All three new notebooks will reach retailers in March.
