The MBA canera is more than OK for Zoom calls and the battery easily lasts the whole day.
Also, a lot of the medical schools have gone the virtual machine route due to privacy concerns (patient information, medical software licensing, etc). Most of the med students / residents get access to their own Windows virtual machine (VCS) that can be accessed over the internet through Citrix or equivalent. All the student work (Word, presentations, research, patient data) will basically happen inside that virtual machine and all the info is stored in the Univeristy cloud and backed up on the University servers. Nothing should actually be stored on the personal laptops, especially patient related info due to privacy and safety concerns. This is emphasized multiple times by the University IT department. I think most of the medical schools will go this route because all the expensive software will be purchased by the University directly and made available to all the students and residents free of charge inside the Virtual Machine. Normally everything that a student needs will be available in the VCS and no additional software will need to be bought (Word, Mail, Powerpoint, SPSS, Medical Imaging software, etc)
So the laptop will basically serve as a point of access for the virtual machine and that's basically it when it comes to student work, all the heavy duty processing is done in the cloud. Even a Chromebook with a good screen could work just as well. An iPad 12.9" might work too, but I am not too sure, it all depends how the virtual machine it is accessed. Citrix on iPad was not good, I tried it on my end, the mouse support was terrible and it couldn't really be used to work with the Windows virtual machine.
For healthcare students, the times of personal laptops to be used for school has passed. The focus is on patient privacy and data security and it is much easier to have it all on the University servers and the students access it remotely. There have been cases when students lost their personal laptops and sensitive patient data was compromised, that is a huge liability issue for the Universities and Hospitals. The new norm is centralized cloud access + a remote machine to access it that must have an encrypted SSD.
