* Relion 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. * Improved hard disk technology. Early laptops had only floppy disk drives. As thin, high-capacity hard disk drives with higher reliability and shock resistance and lower power consumption became available, users could store their work on laptop computers and take it with them. See also 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. Among the first commercial IBM-compatible laptops were the IBM PC Convertible, introduced 1986, and the Toshiba T1000 and T1200, introduced 1987. Although limited floppy-based DOS machines (the operating system was stored in ROM), the Toshiba machines were small and light enough to be carried in a backpack, and could be run off lead-acid batteries. These also introduced the now-standard "resume" feature to DOS-based machines; the computer could be paused between sessions, without having to be restarted each time. Another notable computer was the Cambridge Z88, designed by Clive Sinclair, introduced in 1988. About the size of an A4 sheet of paper, it ran on standard batteries, and contained basic spreadsheet, word processing, and communications programs. Although it anticipated the future miniaturization of the portable computer, as a ROM-based machine with a small display it can — like the TRS-80 Model 100 — also be seen as a foreruner of the PDA. * Hewlett Packard - HP Pavilion and HP Omnibook Some parts for a modern laptop have no corresponding part in a desktop computer: * ASUS

* Sony - VAIO * Tablet PC Performance * Packard Bell - EasyNote * 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.

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. Laptops & laptop brands Another claim to be the "first laptop" was made by a novice programmer Thomas Kelly in 1982. While it was made to be used upon one's lap, it weighed 150 pounds, and therefore could not be deemed truly portable. * Clevo * Improved interconnectivity. Internal modems and standard serial, parallel, and PS/2 ports on IBM PC-compatible laptops made it easier to work away from home; the addition of Ethernet networking ports and, from 1997, USB, and from 1999, Wi-Fi, made laptops as easy to use with peripherals as a desktop computer. * ASUS * Most modern laptops use an active matrix display with resolutions of 1024 by 768 pixels (XGA) and above, screen sizes 10 inch (250 mm) or larger, and have a PC-Card expansion bay for expansion cards, formerly called PCMCIA. Internal hard disks are physically smaller—2.5 inch (64 mm) compared to the standard desktop 3.5 inch (90 mm) drive—and usually have lower performance and power consumption. Display adapters and sound cards are integrated. Modern laptops can often handle sophisticated games, but tend to be limited by their fixed screen resolution and display adapter type. * Portable computer

* Improved liquid crystal display design, in particular active-matrix display technology, and increasingly, color screens. Early laptop screens were black and white or grayscale passive-matrix LCD displays prone to heavy shadows and blurry movement (some portable computer screens were sharper monochrome plasma displays, but these drew too much current to be powered by batteries). Improvements in production technology meant displays became larger, sharper, had higher display resolution, and could display color with great accuracy, making them an acceptable substitute for a traditional CRT monitor. * Sony - VAIO * Notebook Among the first commercial IBM-compatible laptops were the IBM PC Convertible, introduced 1986, and the Toshiba T1000 and T1200, introduced 1987.

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.
