High x heights were considered more legible for low-resolution displays (though I'm not sure if the evidence was there or if it was just something that sounded sensible) but have not been considered good with high resolution ever I think.
Think something like Verdana (invented for low-res computer displays) vs Garamond (staple for a long time and not just because it looks pretty.)
