I don't get why so many people like the ThinkPad X1 Carbon. They don't come with SODIMM slots, RAM is soldered directly to the board. If RAM goes bad, you have to do circuit level repair which requires a potential reball. The X1 Extreme comes with SODIMM slots from what I hear, but that is not the X1 Carbon. It certainly won't be lasting anywhere as long as previous Thinkpad models that have replaceable parts.
I'm probably going to get an M2 Max MBP when available and max out most of the specs. I think it'll be the first laptop I'll have bought new. Lots of soldered parts, yeah, but that's the norm with ARM anyway. Hopefully the M2 Max will stay usable a good decade or so and there'll be more RISC-V options after that.
