LAPTOP
History
As the personal computer became feasible in the early 1970s, the idea of a portable personal computer followed; in particular, a "personal, portable information manipulator" was envisioned by Alan Kay at Xerox PARC in 1968 and described in his 1972 paper as the "Dynabook". The first commercially available portable computer appeared nine years later, in 1981. The general terms "laptop" or "notebook" can be used to refer to a number of classes of small portable computers.

As replacement. A desktop replacement computer is a laptop that provides most of the capabilities of a desktop computer, with a similar level of performance. Desktop replacements are usually larger and heavier than standard laptops. They contain more powerful components and numerous ports, and have a 15.4" or larger display. Because of their bulk, they are not as portable as other laptops and their operation time on batteries is typically shorter.

Advantages
Portability is usually the first feature mentioned in any comparison of laptops versus desktop PCs^. Portability means that a laptop can be used in many places - not only at home and at the office, but also during commuting and flights, in coffee shops, in lecture halls and libraries, at clients' location or at a meeting room, etc. The portability feature offers several distinct advantages: Getting more done, Immediacy, Up-to-date information, Connectivity,

Being expensive, common and portable, laptops are prized targets for theft. The cost of the stolen business or personal data and of the resulting problems (identity theft, credit card fraud, breach of privacy laws) can be many times the value of the stolen laptop itself. Therefore, both physical protection of laptops and the safeguarding of data contained on them are of the highest importance.

Actually the laptop is important because we need do different activities at university, home and other places.
