I am looking for a cheap, light, tough, relatively fast laptop to replace my decade-old lenovo. It will be my daily computer for browsing, documents and occasional photo editing. I will install eitherUbuntu or Mint.
I am looking at thinkpad x13 gen 1. It looks like the processor has an impact on the way it will be running, with different performances between ARM AMD and Intel.
Can I buy either one or I there a real compatibility issue with intel?


You mean AMD or Intel? I can’t find any variant with an ARM processor. According to the internet, both the Intel and AMD version should work with Linux. My wife actually owns the Intel X13 Gen1. With Linux Mint Debian edition on it. Seems to work fine, she didn’t ever complain. Just be aware these are 5 year old devices. She paid 404€ for a refurbished one. We went with the 16GB RAM option, since that’s soldered and not upgradable. Also had an i7 processor at that price point.
Yes, sorry I meant AMD. Thanks for all the precious info!
