Given your other post today about pwning, I don't think I'd touch this offer with a ten foot pole. If this were for a one-time purchase, Adobe could use one's credit card information for the purchase and then discard everything but the last four digits to display for your records. With this perpetual subscription, though, that means Adobe will have to keep your full credit card details on file so they can make that charge to your card every month.
Given Adobe's past track record, they've never been one to react and correct their mistakes in a lightning quick manner.
But don't mind me. I'm one of those old curmudgeons who looks upon cloud computing with great disdain. The potential is there, but it's still too new and companies are pouring all of their resources into trying to find ways towards the perpetual billing of customers rather than concentrating on security and the securing of the data they are so eager to store.
