Everyone is saying lenovo, and while I don’t disagree, I really wish my T480 had a nicer bottom clamshell. If you want to swap a drive or ram you have to take the whole bottom off. Cue tiny plastic clips breaking. I’ve seen decent laptops with the cutouts and a single screw on the bottom for swapping ssds and ram. Those are awesome. Lenovo should do that. I say this because I like to distro hop on my laptop. I wish I could keep a drive with a linux OS that I like and have setup, but then swap out blank drives for distro hopping, play around, and go back if I want. But the bottom prevents me from doing it easily.
