Laptop for sixth form - recommendations?

[happylittlebirdy]

Hi. My DC school is moving from iPads to windows devices so we need to get something new for 6th form. These are the requirements:

touch screen
detachable or flip screen to enable flat writing using a stylus
keyboard

also some technical specs but we can check these.

Can anyone recommend something that fits the bill? The detachable/flip screen in particular seems quite limiting…

Surface pro? Mine is 6 years old and going strong still. It's particularly useful for writing formulae etc in studying sciences.
