What this analysis is missing, is that there are multiple times more iOS users (and therefore potential customers) than there are Mac Users. They set a lower price on iOS with a hope for making it up in unit volume. However, they're realizing now that unit volume being similar to Mac, prices must go up. I agree it's not as valuable a platform as the Mac, but it's also probably not 1/5 as valuable.
