They clearly have some real-world kerning tuning to do, but I don't know if that will happen given their "look at our perfect new font" campaign.
Let's hope the font nerds deep in the bowels of Apple will do the right thing and tune it over time.
("Doing the right thing in the bowels" reminds me of a story an old friend of mine told me years back. He was an Apple fellow by that point, one of a handful, able to work on whatever he wanted. (He was in the printing group, since he came out of Imagen, the TeX project laser printer spin-off, where we both worked.) Anyway, at some point Jobs went off on a rave at a meeting and declared that fax was dead, and they should no longer support faxing in their printer drivers. Chen and crew had no choice but to fold in public, but kept it in anyway, and Job was never the wiser.)
Helvetica is a typeface designed for signage, headings, posters, corporate logos, and the like. For body copy, it’s terrible, because it has a strong boxy/griddy quality to it, many similar looking letters, and proportions which make letter shapes hard to see at small sizes.
For my taste San Francisco looks a bit too blocky due to the flattened curves along the vertical axis. It's not bad, but I like Google's Roboto typeface, for example, better.
