I've rented a number of Nisson's that have this and it is a really cool feature.
With the XF if you have to insert the key anyway, it is a waste of time and money.
Ferraris, Lambos and other notables have had this Key & Button setup for years. That, and the S2000. It's just a racy feature that is cool. It obviously serves no practical purpose. It is cool though. I would do it if it turns out to be "plug and Play". I wouldn't do it if wire hacking was necessary.
