Do you need a laptop if you already have a PC and an iPad Pro to study?
You can study faster and more efficiently while on the move - if you master ten-finger typing, for example.
There are already dozens of keyboards for the iPad pro and in May a new one will be released by Apple (;

I have had bad experiences with android. My first iPad 4 still works okay after 7 years.
At least not with my iPad. Lasts easily for many days if I don't use it as intensely.
