It's crazy, I ordered two macbook pro M4 14 inch machines - the second because I made the mistake of buying the 'nano texture' display - which - just like a cheap $5 'matte' screen protector you might buy for your iphone - makes the screen blurry, lower contrast, and slightly crystalline.
The original one, I'm returning because of the screen, had a GREAT keyboard. I liked it more than my outgoing M3. I can't remember what my M1 was like, but this M4's keyboard had great travel, and was easy to type on. It was predictable, gave great feedback, and even the trackpad was great.
The new one I got without the scam matte screen protector attached - I hate the keyboard. Tiny travel, way too soft, no feedback - I'm making tons of mistakes all the time. To the point where I kind of have to return it. It's basically the worst keyboard I've ever had on any device. Interestingly, the rubber seal around the screen - it's about 1.5mm thinner on this new machine than my first.
BUT even that second keyboard doesn't have the 'clicky' issue described by others here, which makes me super scared that actually even my second one was one of the 'good' ones.
Its insane to me how different these machines are.
Also - FWIW - the screen is slightly dimmer and more yellow by default, on both, than my M3.
