It is in the heading
Laptop, good, 300 euro?
You're particularly funny today, aren't you?
You should already know what you are going to do with it. Almost any x is sufficient for Office only.
If you also like games, of course, the equipment should be a bit higher. And 300 euro will probably not be enough. And I don't mean relatively complex games. Since it should already be a laptop around 1000 euro.
You should also dig a little deeper into your pocket for photos or video editing.
Good laptops are only available in this price range as professionally prepared used devices.
What exactly is "good" always depends on personal needs. Depending on the usage, the laptop must be able to do different things.
No, I play Sims from time to time, but the main thing is to write
You think it's funny that there are people who have to live on little money?
Then you can take the one you like best from the feeling. Don't expect too much from the performance. But it should be enough for Office.
It's certainly not funny, but you can't get something "good" as a laptop for 300 euro.
