On this chart, a StoreBoard ranking of the five top-selling portable PCs in units sold over a recent five-month period, a number of points are worth noting. First, it's a surprise that any system with a color active-matrix display would rank here at all, as does the Compaq LTE Lite 4/25C. Second, our survey is a small sign that major system vendors on the PC side are overcoming supply problems. Compaq is among these vendors, and the IBM ThinkPad 720C ranks in the top 10, although it is not listed here. The presence of three PowerBooks in the top five is no surprise, given the runner-up Readers' Choice award BYTE readers gave this line last spring. Infocorp analyst Kim Brown estimates that 2 million notebooks with dual-scan, passive-matrix displays will s
hip in the coming year--one of them, the Contura, already leads the pack in sales. Passive-matrix screens should find continued competition from active-matrix screens. A report by Frost & Sullivan, noting that in June 1993 the U.S. Department of Commerce ended tariffs on imported active-matrix screens, predicts lower prices for active-matrix screens and fewer backlogs.
Prices given are estimated street prices. For Apple, they range according to configuration. The "Possible features" column represents BYTE editors' most reasonable presumptions as to what the next generation of these systems might offer, based on established vendor patterns and market pressures.
