I use first@firstlast.com and wasn't able to get the firstlast@gmail.com so I guess I'm just hoping I'm getting all my email. I will say that having my name be my email makes life /so much/ easier. Especially over the phone, "Yes, my email is first@firstlast.com, just like the name I just told you and/or is already on your screen when you pulled up my account".
I also have firstmiddlelast@gmail.com, and about half the time I tell someone my email address, the send it to the gmail one.
