Portability is usually the first feature mentioned in any comparison of laptops versus desktop pcs.Physical portability allows 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:
a. Productivity: Using a laptop in places where a desktop PC cannot be used, and at times that would otherwise be wasted. For example, an office worker is managing their e-mails during an hour-long commute by train, or a student doing his/her homework at the university coffee shop during a break between lectures.
b. Immediacy: Carrying a laptop means having instant access to various information, personal and work files. Immediacy allows better collaboration between coworkers or students, as a laptop can be flipped open to present a problem or a solution anytime, anywhere.
c. Up-to-date information: If a person has more than one desktop PC, a problem of synchronization arises: changes made on one computer are not automatically propagated to the others. There are ways to resolve this problem, including physical transfer of updated files (using a USB flash memory stick or cdrs) or using synchronization software over the Internet. However, using a single laptop at both locations avoids the problem entirely, as the files exist in a single location and are always up-to-date.
d. Connectivity: A proliferation of Wi-Fi wireless networks and cellular broadband data services (HSDPA, EVDO and others) combined with a near-ubiquitous support by laptops means that a laptop can have easy Internet and local network connectivity while remaining mobile. Wi-Fi networks and laptop programs are especially widespread at university campuses.[

e. Size: Laptops are smaller than desktop pcs. This is
