1. Not all software is available in the repos, in some distros this happens frequently. And no, it doesn't "just work", I've even tried a popular distro that destroyed itself with the first update on a clean install. 2. I invite you to try an Nvidia Optimus setup. Good luck and hope you don't end up with a black screen because your distro thought it can handle it but doesn't. 3. Even if that was easy, most people trying out Linux do so with the hardware they currently have. And more often than not this means broken suspend or wifi or... 4. We have pretty cheap 4k screens nowadays and laptops with 4k. It's not that uncommon. 6. Are you seriously implying distros inheriting from another are all compatible with each other?
