I'm postively surprised. I didn't expect this from Apple, but it actually does look good with the Windows font renderer here (Firefox, so I assume DirectWrite), down to at least 9px. The hinting could perhaps be better on a few letters but I expected none care taken whatsoever. Of course, this could be a lucky accident, not sure if Apple did this intentionally. The thin weights seem OK as well, something else that can not always be expected. Looks decent for general use unless Apple prevents that by licensing.<p>I never liked Helvetica Neue in user interfaces so I'm happy to soon (hopefully) see it gone from iOS.<p>Edit: OK, so it's only to be used by either Apple or Apple apps.
