I have T460. I like the fact that it has two batteries, good casing, great touchpad (unlike the one that I've had on T440s), holes for liquid drainage... When you put SSD into it, and have 16GB of RAM I don't see it lagging behind more modern ThinkPads. In my opinion, new is not always batter :) The only thing that I miss on my T460 is better graphic adapter. I have Intel HD but even with it I can play games up to Fry Cry 4, Call od Duty 4, etc.
I’ve got the T470 (as it has the old docking + charging port PLUS thunderbolt), modded it with the N140HCG-GQ2 panel (1080p, 100% sRGB, 400 nits, 8bit), with a 2TB NVMe SSD, 32GB of DDR4-2400MHz RAM, etc. I've got two 75Wh batteries I can switch between.
Overall I get great performance even for stuff like running IDEA and a spring web app in a docker container, and I get 13h+ of battery life out of it (+10h if I switch the external battery to the second one I keep in my laptop bag).
I'd wish the 30th anniversary thinkpad (coming this year) will be just an upgraded T25 with a modern ryzen processor but in every other way identical (I know, an unrealistic dream)
I have a Ultra dock for a long time now... And I know that if I ever upgrade from T460 to the T470 will be the last model for quite some time. This is the last one that fits onto my existing docking station. I must say that I prefer mechanical docks over USB/TB and other types.
