There is a misconception about computers that is, they would be soon replaced by the laptops. The reality is actually the opposite, computers are not going anywhere and there is a huge majority of people who actually prefer to work on desktop computers than a laptop.
I know laptops have their own benefits but they are cannot replace the computers for sure. For example, the majority of professional have the habit of sitting at a desk for work, not everyone can put the device on a laptop or take it to bed.
For every laptop owner, the biggest issue is to have a laptop that has an issue and can not be fixed.
In most cases, if there is nothing wrong with the keyboard, an additional keyboard can be attached or if the touchpad is not working fine, this can be fixed too.
However, if there is something wrong with the LCD, the additional monitor will be attached that destroys the portability of the laptop.
Being the most sensitive and yet most useful.
Additionally, without the proper working of LCD, user can not work properly and opening this on your own can be a bit risky.
