As far as I can see, the T440p is the latest Thinkpad to support Coreboot/skulls.
If I wanted something newer (say, something from 2019-2022 or so) under $400, what could I even get? I want to run my own choice of linux distribution on it, so most chromebooks are out of the question (also I'd like something more powerful and upgradeable).
Thanks.
While it doesn't satisfy the "under $400"-condition, I couldn't withhold myself from mentioning the likes of NovaCustom and Tuxedo. For the fact that both have been absent from the conversation while they otherwise satisfy the requirement of coreboot on a modern device. With the former, NovaCustom, being arguably the best vendor to buy 'privacy&security'-first devices with modern hardware from. Not for their entire line -mind you- but specifically their NV41 Series; which is -to my knowledge- the only Qubes-certified computer with modern specs and Heads. However (with Qubes and Heads pre-installed) it starts at $1224, which makes it considerably more expensive that your stated target (read: under $400).
Thank you. I had heard of these vendors before and will keep them in mind going forward, if I need such hardware. For now, I'm planning to settle for some 6th generation Intel and run me_cleaner on it. Thanks again
