I have not had the same problems and dilemmas as you, but I sympathize with you. Regarding the choice between a computer and a laptop, I would suggest you use a laptop https://www.apple.com/mac/ for university, this is still a more practical option. When you will need to, you can bring it directly to lessons, print or present any information, in general it is very convenient to use and its battery can last the entire day at university.
