The entire reason Apple made devices that were a level above competitors is because the design wasn’t just the aesthetic. Ive was chief designer and so obviously had a key impact.
It might be a complete misinterpretation but it seems like Ive went completely haywire when Job's was gone with the ultra thin, portless, overheating Macs with a crappy keyboards and pointless touch bars that sort of looked cool but provided no other real value.
Key impact like the shit emoji keyboard that couldn't survive a single speck of dust?
How do you know Ive had a key impact? Do you know it or read somewhere online?
“How do you know that <primary responsible person> had impact”.
Do you hear yourself?
Then all OP is saying key impact person had key impact. Doesn't add any substance to discussion.
Neither did your second sentence, and you still wrote it. Sometimes we write things down to draw attention to the fact, not to inform a naive audience of facts that they did not know.
