Which 2in1 laptop?

I would like a laptop with a keyboard that can be removed. I would like a laptop with the features:

Slot: at least 1 USB2 or USB3

RAM: at least 4GB RAM

Internal hard drive: at least 250 GB

Operating system: Windwos 7 (or newer) or OSX 10.7 (or newer)

Battery power: at least 6 hours

Since I'm a student, the price of the laptop should be less than 700 euro.

What happened to your Surface Go?

I would also be interested in alternatives

Classically 2in1 means a system in which the keyboard side is only folded over and the system is therefore very bulky in tablet mode. Do you want that or should it remain a removable keyboard?

The removable keyboard should remain. Because I need a laptop for university and want to watch Netflix at home.

Then you are in good hands with your Surface Go, because there are no alternatives in the Windows world. Except, of course, the larger SurfaceTablets. But for 700 euro you can't get a Surface Pro with Type Cover.

Then I'll buy the Surface Go.
