Exceedingly legible on mine even at 7-8pt sizes, but I should note that I'm very accustomed to reading Garamond and may be inferring more. I know my first impression from the iPhone 4 was that it was blurry; I think this is because I could no longer see the pixels, which I had apparently been subtly keying off. It is definitely not blurry, but still sometimes disorients me.
