Odds are they will bundle a laptop with your tuition or really ask you not to use apple laptops.
Been my experience so far. If they require one, they make you buy it. If they just want you to have some minimum specs, its windows.
If you are in your beginning years of undergrad, just buy whatever. New or old, but it sounds like new is the way to go for warranty and likelihood to replace instead of repair.
But if you are close to getting into medical school, look at the laptop requirements.
Boot Camp, VMWare Fusion, Paralells or a combination of these can all provide perfectly acceptable alternatives to a Windows only notebook.
The companies I work for often have varying requirements for onsite equipment and I've been using separate disk images for these for several years. Virtual machines just make this easier.
