In a nice article in "APC Mag":http://apcmag.com/4872/microsoft_takes_on_gmail_in_the_workplace_2gb_mailboxes they discuss how the standard corporate user is sick of these tiny email quotas and are just forwarding their things to gmail (and making Microsoft exchange redundant). nothing too new in the product announcement, but the comments are interesting.
