" ... flexibility ... blah blah blah ... flexibility ... blah blah blah ... tighter integration [ ! ? ]" Huh?

There is a difference between integration and interoperation, isn't there? Because I think I want the one and not the other. But this guy seems to be saying I want the one I thought I don't want. Now I'm all confused. I guess I better go ahead and pony up the money to someone who's more certain, then.
