BEBOP,
You will be pleased with your purchase. I have used the same setup in my E80 and in my laptop. The adaptor for Compact Flash is cheaper and exactly the same size as the multi-format adaptors that take SD cards, so I think it is the obvious choice.
I am curious about SD capability because I have ordered the Technote styles which come on a SD card. Although I will probably end up transferring them to a Compact Flash Card, it may be handy to use the SD card directly. I also have a large supply of SD cards for my KN7000.
Let me know if you are as happy with your E80 as I am with mine!
