There are too many different types of laptops and different price categories to adapt them. This is because the size of a laptop's screen also determines the overall size of its chassis. A laptop with a huge 17-inch screen will be great for work and games, and is likely to feature a decent sized keyboard for easy typing, but will be much bigger and heavier than a 13-inch model.
You will be watching your portable computer for many hours every day, so you want to make sure you have a screen that is comfortable to watch. Nowadays, many laptops also have touch screens, which means they are brilliant. Bright screens lead to reflections, so think of a laptop that does not have a touch screen.
Also known as RAM, it allows you to do many things at the same time. 4 GB should be the minimum so you do not have to worry about the number of browser tabs you have open at the same time. If you are going to edit videos, you will need at least 8GB. That said 8 GB of RAM is the most important.
Small, lightweight notebooks typically offer greater autonomy over larger models because they have lower-power, lower-voltage processors and a smaller display.
