Which one would you recommend? Laptop

For school, tasks, applications, etc.

The first because it has Windows as its operating system, where there's probably the greatest variety of programs. Of course it depends on what you want to do with it.

Everything in this price range is electronic waste.

You're only looking for something for school, but I would buy this one:

In the notebook, too, the graphics card, CPU and RAM are the core of the unit. The rest are just bells and whistles.

Compare the offers from Amazon with the site or a provider you trust.

For 500 euro you can get one like this:
