Tablet with 4GB RAM?

My question is already rudimentary in the title and I want to buy a tablet for school.

I have now selected the Microsoft Surface go 2. That has 4GB of RAM and 64GB of storage. I'm not afraid of the memory because I can simply buy an SD card.

But is 4GB RAM enough?

It should just run smoothly when I e.g. Create files, create presentations, research, Netflix

4GB ram is enough but I would recommend you to buy a tablet with 8GB, since windows without applications c.a. 2.5 GB needs.

Oh well, okay.
