Portability is usually the first feature mentioned in any comparison of laptops versus desktop PCs.46 Physical portability allows a laptop to 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' locations or at a meeting rooms, etc. The portability feature offers several distinct advantages: Productivity: Using a laptop in places where a desktop PC cannot be used can help employees and students to increase their productivity on work or school tasks. For example, an office worker reading her work e-mails during an hour-long commute by train, or a student doing her homework at the university coffee shop during a break between lectures. Immediacy: Carrying a laptop means having instant access to information, personal and work files.
This allows better collaboration between coworkers or students, as a laptop can be flipped open to look at a report, document, spreadsheet or presentation anytime and anywhere. 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, transporting a single laptop to both locations avoids the problem entirely, as the files exist in a single location and are always up-to-date. Connectivity: In the 2010s, a proliferation of Wi-Fi wireless networks and cellular broadband data services (HSDPA, EVDO and others) in many urban centers combined with a near-ubiquitous support by modern laptops48 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.Źródło: https://en.wikipedia.org/wiki/Laptop#Advantages
