All that means is that users on those devices willl see you fallback fonts instead.
This saddens me, as I’ve lately been doing more and more of my casual surfing on an iPad. I think that the web is about to become a much more visually interresting place, and I’ll be missing out on it.
So the question is: who blinks first? Apple and Google are becoming cutthroat competitors, so I’m not sure if there will ever be a happy solution for users.
Ultimately, I’d like to see Apple add the support to their mobile Safari browsers than the other way around. I think that is better for the development community at large, and will benefit the users the most in the long term.
