Hi, does it make sense to buy a tablet or laptop for studying applied computer science? What would you advise me?
First a laptop
And then later the tablet?
For a computer scientist, a tablet is roughly the value of a cutting board.
I would definitely recommend a Windows laptop. There will be very few incompatibilities on it. You also have a Linux with you with WSL.
Tablet
Ask yourself what would you rather program for? That will definitely be part of your studies.
I would recommend a laptop with Windows 10 because that's where the software offer is the largest. For example this: https://direktkauf.idealo.de/productpage/200406422?siteid=1&offerKey=081475867341140e53997f935833ca89&osId=3338284010687168638&shopping=1 Windows 10 is included.
