Which 2in1 tablet should I buy?

So I've been writing in my laptop for a while now, but with the science students (maths, chemistry, bio and physics) formulas and drawings are getting harder and harder to get along with the laptop. So I'm looking for a tablet with pen and removable keyboard for less than 500 euro. Since I'm also a musician, I would use the tablet as a digital music folder and should therefore be over 10 inches tall. Operating system should be Windows or Android

With 500 euro, the new is rather difficult

No, you should be able to remove the keyboard and not fold over

I think it should be at least 2 things together so tablet + pen or + keyboard

The keyboard is the original Anstecktastaur of Samsung matching the S5e, but there's only one to buy, the same with the pen

No then not

I do not really understand, I have the tablet myself for 2 months and I'm excited about it, and what better for the price, you will not find.
