Thinkpads are cheap and accessible basically everywhere. They are business-grade devices and you can get one when folks retire their machines. A lot of places practically give them away. They were just gonna get thrown out anyways.
Framework is dumb expensive - a 16 even skimping out on RAM/HDDs comes out to over 3k CAD, and that’s for a disassembled kit – pre-built with full components comes out to easily over 3.5k, which is like a MacBook price for the promise of upgradability down the line.
System76 are rebranded shitty components from Chinese manufacturers. They’re not better for Linux than any general consumer laptop, and their entire position is basically branding regarding freedom and 1776. Ironic that a company so deeply American in nature basically just resells garbage from China.
