ThinkPad forum/subreddit got a bunch of reviews, when Retro shipped.
The keyboard does have the old layout and I get that some people like it… I, for one, couldn't care less.
Mechanically, it's not the same though. Actually, the same as what? Each thinkpad model/generation has had a slightly different keyboard, sometimes made by a different OEM. There was a notable difference between keyboards for the same model, but from Chicony and, say, NMB.
One major change is keycap texture, which is way smoother out of the box than back in the day.
Either way, I can't justify getting a T470 with a different logo and keyboard layout (that I don't care about), and the stock was extremely limited in Europe anyway.
