My own personal emails are all towards the random end of the scale. Few contain any part of my natural name and absolutely none contain two parts. So the Apple approach is not that different for me.Have enjoyed and used this feature a lot since it came out
My one wish would be to have the option of less "random" emails as I like using them when emailing companies or signing up for things where I need to have my real name, but not email. Makes it weird giving/memorizing such random emails but I guess that is the point of it
Many years ago, I went through a phase of creating email addresses for each company. Hence would have produced macrumors@<mydomain> for this site. Rather neatly that identified how any email addresses might have been passed on. But it lets people know too much because <mydomain>was too informative (e.g. Whois records).
