If they don't give you a choice of Mobi vs Adobe, then you'd also be losing any future updates/fixes. It would be nice if (hypothetically) 1.8 is the Adobe udpate, that it's optional. Then when 1.9 comes out there is a 1.9-mobi and a 1.9-adobe, so that customer's have the choice of which format they prefer.
I have no idea if they're going to do that though, just wishful thinking on my part.
