I'm using an X220 which is even older than the T430. It is on its last legs and its keyboard doesn't work at all (using an external) but I feel that it is fast enough in terms of cpu, storage, etc. I do some programming on it but it is not a hardcore dev box. I use remote servers for that. I don't feel like I need multiple disk drives: if I want to back up on the same machine, 1TB microsdxc cards are a thing (in fact I only need 256gb or so). I need to replace the X220 quite soon and there are way fewer used Thinkpads on Craigslist than there used to be (any vintage, not just that era). I don't know why that is. But I agree with the article that the newer stuff is way too crapified and that the 2012 era machines are about the best ones to use right now. Older ones were even more solidly constructed, but had DDR2 memory, considerably slower processors, etc. So I will probably look for another X220. (X230 is similar and a little newer, but has the silly 6 row keyboard instead of the nicer old 7 row one).
