You have to remember that this isn't aimed at a typographer, its aimed at people who perceive text differently. size isn't always the answer.

Obviously its not going to be the next zilvertype. That to one side, I am curious to hear from people to see if it helps.

I get the intention, and if it wasn't obvious in my previous post; I have dyslexia. Font sizing on computer screens is complex, fonts don't scale perfectly, they have sweet spots where line thickness spills over. When you configure ClearType on Windows it's quite evident where curtain parts of curtain words spill over (a similar fashion to Open Dyslexic actually). Looking at different sized text, it's the line thickness that aids readability rather than the size of the font.

I pretty sure this is the basis of why serif fonts aren't as readable on computer displays, the serifs add more noise rather than help.
