A 4-pound notebook is developed by Sharp

Article Abstract:

Sharp Electronics Corp introduces a four-pound notebook-style portable microcomputer. People who have seen it say the product has a display screen that is superior to most other portables. There is, they say, an internal hard disk that can store 20Mbytes, and the product runs on an 80286 microprocessor. The new Sharp PC-6220 is expected to cost less than $4,000. The company is announcing the product now, even though it will not ship until Jun 1990, apparently hoping to get the jump on other notebooks expected soon from rivals. Some questions about the PC-6220 remain. Notebook computers often have cramped and stiff keyboards, and though Sharp asserts that the PC-6220 has a good one, the machine's 8.5-by-11-inch format suggests that compromises may have been made. The PC-6220's battery life is only two hours; Sharp offers an add-on battery that raises operating life to five hours, but increases the weight to six pounds.

The portable Mac: sharp, but heavy

Article Abstract:

Apple introduces the Macintosh Portable, which costs between $5,799 and $7,000 depending on the features. Though other portables running Macintosh software are available, this is the first machine made by Apple, which should cause corporate buyers to prefer it. The machine weighs 16 pounds, considerable more than other portables. Most the weight is due to Apple's use of the longer lasting and more reliable lead-acid battery, which can power the Portable for eight to 10 hours between recharges. The display screen is the largest and the sharpest available on a portable, utilizing active matrix liquid crystal display technology. Each pixel is powered by its own transistor. The keyboard incorporates a trackball to replace the popular mouse, and a Video Adapter will be available soon, allowing the Portable to be connected to a television set for large screen presentations.
