I used the base iPad + Apple Pencil throughout preclinical. I used it for notes and an anatomy app for learning anatomy. I’m not sure if it’s necessary for notes but I personally found the 3d anatomy app pretty helpful, although it’s available for computers and phones too. Definitely using it a lot less during clinicals. In summary I guess I’d say it’s nice but not necessary so I wouldnt splurge for the crazy expensive ones. As a side bonus it’s a decent e reader if you’re into that, albeit expensive and not great in direct sunlight.
