It will depend a bit on your class structure and requirements. For preclinical, I enjoyed having a 2-in-1 with a stylus so that I could type most things but draw when it was more efficient (histology, anatomy, radiology). For the wards, I only used my own computer when there wasn't a hospital desktop around and I never had it on rounds. Some people recommend a small iPad for rounds, but I never felt like it would have been helpful.
The above will suit you fine and is what most people do. But, if you're someone who studies at home, I would highly recommend getting a bigger desk with desktop of some sort, or at least a laptop that allows you to connect a big monitor. I decided to finally get a desktop when I was stuck at home for COVID, and my efficiency has skyrocketed by being able to work on a bigger screen while simultaneously being able to use my laptop. Things like streaming lectures while taking notes, watching Pathoma while organizing your Anki deck, etc. are far easier with some kind of two screen setup. Again, not a requirement, and I did just fine in preclinical without this setup, but now that I have it I wish that I had done it earlier.
