I'm new to this conversation, but I have the same reaction as mark212. The purpose of quoting an interest rate is so borrowers can (a) predict how much they will have to pay back and (b) compare one loan against another. The first purpose is better served by the flat-rate quotation, and the second is also better served if most other lenders in their community also quote flat-rate interest.
