QuietLion's point is well taken. You can still transfer in amounts of less than 20K to top off accounts, etc., you just don't get the 5K bonus. And since this Starwood/Sheraton AMEX is FREE, it's a no-brainer for me. (I did, however, get the Delta Platinum to get the 15,000 sign-up, and the 50,000 bonus for spending $10,000 in the first year. Don't know if I will keep it after that, although the double miles is an attractive feature.)
