So "user acquisition" isn't really a concern for us, though frankly, I believe it should be. And until it is, I guess we really can't complain about the flak we get for being "copycats".
And for what it's worth, I am an active user of both OS X and elementary OS and Switchboard feels 105% native on elementary OS. They each feel right in their native environment. Then again, I'm about as biased as possible (though I'd like to imagine my views are somewhat normative ;)).
