Thats one thing Jobs did very well.
He understood that things had to perform and appear right in the real world. the Floor tile example just emphasizes that.
Sometimes what looks the best, isn't always the right choice for the real world for other reasons.
I think this current 'scuffgate' is an example of that. Yes, the black ionodized aluminium looks amazing, But if it's inable to cope with everyday "scuffing and dings" well, it's clearly not the best choice. Choosing something purely for looks over function was something even Jobs didnt do. it was an all together package.
Something that I'm not sure the current top brass seem to understand just yet.
Have you ever seen an older iPod? It's also believed Steve had a lot of input on the iPhone 5 design.
