That's cool. I'm just surprised that a large company wouldn't have already had an Exchange server in the first place. Weird to be sending out emails ending at @me.com (or @mac.com) vs. @verylargeandbigtimelawfirm.com.
I agree. One of the most well-known firms whom my brother-in-law works for just ordered about 10 3G iPhones and issued the .me accounts to all lawyers but they also kept their @thelawfirm emails
