Facebook lets you send email, not receive. I've always hoped they'd make an email system, if only because they've shown themselves to be experts at avoiding clutter.
On the other hand, if a good fraction of users were to get theirname@facebook.com, then the rest had variations on that theme, suddenly sending email to people would be much easier.
I'm happy with my @me, so I guess I won't worry about it too much.
