Out of curiosity, what is the point of the SPG Business considering that there is a better signup bonus with the personal? (That said, I may yet sign up for the Biz now that Amex's new rules have come into play)

On a different note, finally got my Amex Biz Gold 40K a full month and a half after hitting the minimum spend. Gotta give Amex credit, unlike TD who you have to doggedly pursue sometimes, Amex always seems to cough it up within the stipulated timeframe.
