By the end of the 1980s, laptop computers were becoming popular among business people. The NEC Ultralite, released in mid-1989, was perhaps the first notebook computer, weighing just over 2 kg; in lieu of a floppy or hard drive, it contained a 2-megabyte RAM drive, but this reduced its utility as well as its size. The first notebook computers with standard drives were the Compaq LTE series, introduced toward the end of that year. Truly the size of a notebook, they had hard drives and standard-resolution screens. Laptops generally cost more than a desktop computer of similar specification. Performance is usually lower than that of a comparable desktop because of the compromises necessary to keep weight and power consumption low.

* Most laptops are powered or recharged from an external AC converter that usually takes the form of a plain black rectangular box. These devices weigh about 500 g (about 1 lb) and often take the name "power brick." * Notebooks weighing around 5 kg are sometimes termed desknotes (desktop/notebook). * Hypersonic * Fujitsu Siemens - Lifebook, FMV - BiBlo * NEC - VERSA, LaVie * Panasonic - Toughbook,Let's Note(Available only in Japan)

* Docking stations may be used for expanding connectors and quickly connecting many components to the laptop, although they are falling out of favour as laptops' integral capabilities increase and USB allows several peripherals to be connected through one plug. Similarly it is often possible to wirelessly connect a laptop using a cellphone as a modem. Infra-red, USB and Bluetooth solutions are available. The same caveats regarding price of service apply. However this may not remain a misconception for long. Some newer laptops, for example Sony VAIO ultraportables, come with GSM cellphone-based wireless networking capablities, and it is possible to buy add-on PC card GSM modems which provide the same functionality for machines not so equipped. With these, a form of wireless broadband networking is available wherever there is cellphone coverage. Although this is much touted as an ideal business solution, the 'broadband' speeds are low compared to wired connections and the service is prohibitively expensive for most users at the time of writing (1Q 2006). In the US, wireless broadband offered by Cingular and Verizon starts at around $500 for a year with a minimum 2-year contract and each block of data transferred attracts a charge. Unlimited data plans are available but they would normally only appeal to corporate users. A more enduring success was the Compaq Portable, the first product from Compaq, introduced in 1983, by which time the IBM Personal Computer had become the standard platform. Although scarcely more portable than the Osborne machines, and also requiring AC power to run, it ran MS-DOS and was the first true IBM clone. (IBM's own later Portable Computer, which arrived in 1984, was notably less IBM-compatible than the Compaq.) * Winbook * Bacoc * Rock Direct * Desktop computer

Two other noteworthy early laptops were the Sharp PC-5000 (1983) and the Gavilan SC, announced in 1983 but first sold in 1984. The Gavilan was notably the first computer to be marketed as a "laptop." It was also equipped with a pioneering touchpad-like pointing device, installed on a panel above the keyboard. Like the GriD Compass, the Gavilan and the Sharp were housed in clamshell cases, but they were partly IBM-compatible, although primarily running their own system software. Both had LCD displays, and had optional printers that attached to their cases. * Apple Computer - iBook, PowerBook and MacBook Pro The first Apple Computer machine designed to be used on the go was the 1989 Macintosh Portable (although an LCD screen had been an option for the transportable Apple IIc in 1984). Another "luggable," rather than laptop, the Mac Portable was praised for its clear active matrix display and long battery life, but was a poor seller due to its bulk. In the absence of a true Apple laptop, several compatible machines such as the Outbound Laptop were available for Mac users; however, for copyright reasons, the user had to supply a set of Mac ROMs, which usually meant having to buy a new or used Macintosh as well. Laptops are capable of many of the same tasks that desktop computers perform, although they are typically less powerful for the same price. Laptops contain components that are similar to those in their desktop counterparts and perform the same functions but are miniaturized and optimized for mobile use and efficient power consumption. Laptops usually have liquid crystal displays and use SO-DIMM (Small Outline DIMM) modules (rather than the larger DIMMs used in desktop computers) for their RAM. In addition to a built-in keyboard, they may utilize a touchpad (also known as a trackpad) or a pointing stick for input, though an external mouse or keyboard can usually be attached.

Performance is usually lower than that of a comparable desktop because of the compromises necessary to keep weight and power consumption low. * Linuxcertified - Linux laptop 1983 also saw the launch of what was probably the biggest-selling early laptop, the Kyocera Kyotronic 85. Although it was at first a slow seller in Japan, it was quickly licensed by Tandy Corporation, Olivetti, and NEC, who saw its potential and marketed it as the Olivetti M-10, NEC PC-8201, and [1] Radio Shack TRS-80_Model_100_line or Tandy 100. The machines ran on standard AA batteries. The Tandy's internal programs, including a BASIC interpreter, a text editor, and a terminal program, were supplied by Microsoft, and are thought to have been written in part by Bill Gates himself. The computer was not a clamshell, but provided a tiltable 8×40-character LCD screen above a full-travel keyboard. With its internal modem, it was a highly portable communications terminal. Due to its portability, good battery life (and ease of replacement), reliability (it had no moving parts), and low price (as little as US $300), the model was highly regarded, becoming a favorite among journalists. It weighed less than 2 kg (4 lb) with dimensions of 30 x 21.5 x 4.5 cm (12 x 8.5 x 1.75 inches). Initial specs included 8 kb of RAM (expandable to 24 kb) and a 3 MHz processor.
