I think normally when people are referring to buying a ThinkPad they aren’t talking about a modern model. Usually not even the X1 Carbon series; especially past the 6th gen. They’re referring to models in the X,P, or T series before the T490. Models that can be bought relatively cheap and upgraded however the user wants.
The T480 can be bought for around $200. The CPU is going to be a fair amount weaker but for $1,200 some people are willing to make the sacrifice for a casual personal use machine.
