My change would be to offer a redesigned input cover. Bring back home and end keys, and take some inspiration from Thinkpads to have larger arrows with keys for page up and page down (mockup). And add physical buttons to the trackpad. Above or below (or even to the side maybe?) doesn’t matter to me, but it definitely needs to include a middle button. And while I’m at it, give me a led on the mute/F1 key to indicate muted status.
Personally I don’t care about a trackpoint, but throw that in too if it gets enough people wanting to buy it that the redesigned cover is economically feasible.
