There's no LCD subpixel smoothing in iOS, so it shouldn't make a difference.

Perhaps it's just a WebKit bug, but I've definitely noticed this before in an older iPad: http://stackoverflow.com/questions/3220662/uiwebview-font-is...

I've noticed this effect also, and across a number of apps, on both an iPad 4 and an iPad mini. It's most obvious on the mini due to the low pixel density on the iPad mini.

I can't read the mini in portrait mode mostly because I haven't found a font+size combo that I find acceptable.
