I got a thinkpad for $50 at goodwiil. Those linux laptops are so much more expensive. I do plan on buying one soon tho cause I just got a new job

I didn't know about Starlabs but apparently THEY HAVE SHIPMENTS TO MEXICO YES!!! regarding your question these are these major reasons:

• for the most purists, the vendor should have a certificate from FSF saying that "it respects your freedom" a thing that almost no company have (at least that's what I saw in modern vendors)
• in my case and other regions, it's way more probably you can get a Thinkpad easily and more cheap than one from those mentioned

I haven't found one that will reasonably sell me a warranty and that has a good reputation. Warranty cost is a proxy for how likely it will be to break and is insurance against having to shell out another $1k+ over a 3 or 4 year period. System76 is the only one I'd consider and their 3-year warranty is nearly $400. Thinkpad warranties are $150 for the same level of support and $200 for the warranty where they physically fly a person to fix your computer within a couple days.
