Advantages and disadvantages
Compared to laptop computers, tablets are lighter, more portable, have longer battery life, generate less heat, and don't need a mouse or keyboard to be connected - typing is usually done on the touch screen with a "virtual" keyboard which appears on the screen, but some tablets can connect to physical keyboards and computer mice so that they can be used in the same way as a PC. Most tablets allow the user to get notifications even when the tablet is powered off or on standby.
Some disadvantages are that the "virtual" keyboards are sometimes slow and easy to make typos on, and tablets often have limited data storage compared to a laptop. Most run a mobile operating system and often do not support as many file formats and different types of software as laptops, but they may work with the same kinds of mobile apps that smartphones use.
