It is $250 and if you don't have an iPhone it is useless. Do you think you will be plugging your iPad, if you do, where do you plan on keeping it? Plus your iPad would have to be 3G.
I made a mistake by getting BMW Apps. If you have $250 to gamble with or if you think it will be a selling point when it is time (BMW's future support of apps is questionable) then get it. Otherwise skip it.
