When I studied at the uni 5 years ago we only collaborated over Google Docs. I’d strongly recommend online collaboration over sending files back and forth. For most things I ran Linux, and booted into Windows when there was a particular need for it, which wasn’t often. But it all depends on what software you’re expected to run during your studies. If you have room on your drive maybe having a minimal Windows install along side Linux could be a good thing?
Also, I’d recommend a distro that comes out of the box with working BTRFS snapshots. The last thing you want is have the machine you rely on for school shit the bed due to a bad update or something you do, and you have to learn how to repair Linux in the middle of an assignment that’s due tomorrow. With snapshots you can just roll back to before it shat the bed.
I’ve been keeping an eye on Linux since the late 90s. It took me not having to use any non-Linux software or hardware on the computer in question. Currently I have two laptops running Linux, one has Windows in case I need it (which so far has turned out to be never), and I have a workstation that has Linux as a secondary OS but I’m always in Windows on that one because of software and hardware.
