I got a nice deal on the x280 and am happy with it, was also looking at the various X1 carbon. Two criteria I had were I wanted USB-C charging (since I have those chargers around and they can handle these laptops) and a single battery (eg. the T470s I have from work is nice but it has two small capacity batteries that each cost the same to replace as the full size single ones in the carbon and x280). One thing to keep in mind is some of the earlier X1 carbon don’t support NVME SSD (I think it started with 5th gen?)

Edit: another thing to consider is soldered RAM. Part of why my x280 was cheap was it’s only 8gb and can’t be upgraded. Since you’re looking at lighter weight things and using FOSS (and perhaps open to tinkering with things like ZRAM) that might be a useful aspect to focus on because there is probably a glut of such machines given how memory inefficient things are lately with every trivial app running a whole browser engine. OTOH, depending how many tabs you tend to have open and how many electron apps you tend to keep floating around, 8gb might start to feel cramped. Especially if you think you might want some VMs around.

Good point! And ya, when I open umatrix on a comment thread I see a whole menagerie of instances serving me images as I guess that goes for the profile image too.

But I find that somehow less concerning as they just know “someone at this IP viewed this thread containing these images” than “the user at this IP wrote this comment (or post)”.

Hmmm, but if DMs allow images and they work like this, a user with their own instance who wants to know which IP wrote a comment could perhaps send a message to the author with a unique image…
