As a happy ING Direct customer, here are my comments:<p>- I'm extremely jealous of USAA's Deposit@Home feature. Depositing a check just by snapping a photo in an iPhone app? Yes, please.<p>- I've received an answer about the required linked account before, but I still don't like it. ING really can do everything I need from a bank - dealing with another one is just annoying.<p>- It sounds like you two are talking about depositing checks into an ING account by mail? I didn't even know that was possible. The only thing I use my linked checking account for is making deposits and then transferring them to ING. Why isn't this option mentioned in any help topics regarding deposits?
