No, but this is how the iPod beat every other mp3 player -- it was just undefinably better to use. Typography is one of those features; most people don't think they even notice it, but they do.
Your mom might select a kindle fire if she hears from all her savvy friends and family that the kindle fire delivers a better experience. She may even hear why it does, but she may not care about the why, just that trusted sources inform her it is better.
I believe this is true in general. A few savvy people catch on that a product is better and it becomes a meme that others rely upon for their decisions.
Don't talk about my mom like that! (In all honesty she is not really into savvy/hip people;)
I do not think that there are enogh savvy-typography-valuing-people to induce some market driving meme. If this was the case Word would have died many years ago...
