The person you responded to has an AMD framework laptop, which means they can do 96 of ram if they want (some users report success with 128GB). The laptop you linked only goes up to 16GB of ram.

That laptop only has 256GB of storage whereas you can throw a 4TB m.2 ssd into the AMD framework if you want.

That laptop only has 2 USB type-c and they're both only 5Gbps (and one legacy USB port). The AMD 7040 framework has 2 USB4 40Gbps ports and 2 regular USB type-c 3.2 ports (and then the whole modular card system in front of those ports).

That laptop looks genuinely nice. With a few small tweaks I'd consider it. Though, in terms of personal preference I wouldn't want to do a chromebook again because of the annoyance of having to rebind the keys on every operating system I install (the pixelbook had the caps lock key bound to super and IIRC F11 was bound to something that doesn't exist on normal keyboards), and I'll never buy an oled screen for/in a computer.
