Just a quick poll: what type of email username do you have on iCloud? For instance, Gmail users seem to prefer addresses of the form firstname.lastname@gmail.com. Are you guys using similar firstname.lastname@me.com for your iCloud email addresses or do iCloud users have a different preference? (I signed up with MobileMe a long time ago and was fortunate enough to be able to secure firstname@me.com. I also use firstname.lastname as an alias for my more professional correspondence.) * Just a word of caution: due to privacy and spam concerns, you may not want to post your actual addresses here; just the general form (firstname.lastname; firstnameLastInitial, etc.) would suffice.
I was also lucky, a few years bag, to get firstname@me.com for family/friends and firstnamlastname@me.com for formal mail. Only thing I'd like is to get rid of is the .mac address because of spam.
