I pondered it for a few days and decided to take the offer. I am double covered on some of the perks but can cover the AF so it's not that big a deal. Long term I plan on keeping the Platinum and dropping my Delta Reserve for Business once I hit the two spend reward levels (15,000 MQM and miles at $30,000 spend and same thing again at $60,000 spend). I'll keep my personal Delta card just for the first free bag perk. 

Card came in quickly too, got it yesterday in the mail.
