Both is right. The 15 and 16 pro with their glass backs and polished metal bands are super elegant, like expensive HiFi equipment.
The 17 Pro seems to change that refined design narrative to the Air as a statement piece, while bringing the Pro and Max closer to the MacBooks and UltraWatch flair, a more rugged and utilitarian EDC look. Which is ironic considering that a) aluminum is less rugged than steel or titanium and b) the current colorways don’t fit that narrative. I think that perhaps, aside from cooling, repairability, money-saving aspects this was the one way to differentiate Pro and Air. Black or Space gray missing feels like either an abodization problem or a marketing decision to use these colors in 2026. A black or dark grey 17pro will be in line with iPad, MBP and studio (which should be available in black 🙂)
So the 17 is not better or worse, it is a Icomplete rethinking of the Pro design semantics, harkening back to the mBP unibody design — with the usual problems such new paths bring. We will see if Apple paddles back with the 18 or just refines the approach.
I can say that, as with the OS housekeeping, (same numbering, same basic look and feel with Liquid Glass for all aspects of the interface design), it might make sense to unify the design language of the Hardware as well.
