Laptops - defects
The popularity of laptops is understandable due to their functionality and mobility.
Because laptops are smaller than standard computers, iIt is something much more susceptible to damage - if you pour a cup of coffee, the risk of damage to the entire laptop is enormous.
If you pour a cup of coffee on a desktop computer keyboard, you have to replace a keyboard - no need extra help. Laptop can accidentally drop it on the floor, it can be thrown off the desk by a cat, or child.
Desktops due to their size are less susceptible to mechanical damage.
A very important feature of laptops is their portability, which means that it should be fairly light.
Behind this, however, it does not go design - lightweight plastic casing is not sufficiently robust. Servicing these devices is much more expensive and not count on the manufacturer's warranty - it does not cover mechanical damage.

The form of a traditional laptop computer is a clamshell, with a screen on one of its inner sides and a keyboard on the opposite.
It can be easily folded to conserve space while traveling.
The screen and keyboard are inaccessible while closed.
Devices of this form are commonly called a 'traditional laptop' or notebook, particularly if they have a screen size of 11 to 17 inches measured diagonally and run a full-featured operating system like Windows 10, OS X or Linux.
Traditional laptops are the most common form of laptops, although Chromebooks, Ultrabooks, convertibles and 2-in-1s (described below) are becoming more common, with similar performance being achieved in their more portable or affordable forms.Źródło: https://en.wikipedia.org/wiki/Laptop#Traditional_laptop
Laptop - Advantages
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.
