Re: 48px vs 44px target sizing

We've seen studies recommending up to 57px... We went back and forth on 50
px but dropped it to 48px for the very reason you mention regarding Android
devs...  Are you recommending further reduction?

It would make sense for an accessibility standard to take the upper limit
not the lower....

In the absence of any accessibility standard on the size of buttons we've
all followed different measures. I don't think we can take individual
investments into strong consideration when were actually writing the
standard.

I want to read through the study John mentioned... Regarding people with
dexterity issues...

I don't think we can just say "follow platform recommendations"... What are
other's thoughts?
