This laptop good for writing etc?

Is this laptop sufficient to use Word etc? No games, just old-fashioned things

Yes Perfect

The laptop is sufficient for Word, but I would definitely spend more money and buy a laptop with an i5 or Ryzen 5 such as this one.

It is much more expensive but with the cheap one you have to buy a new one in two years because it is too slow

Yes of course the laptop is good for that, but if you don't want to play games, buy a google chrombook. That's still as fast in 5 years as if you bought it today.
