I feel that two blog posts linked in this article touches this subject in an interesting way: http://struct.ca/2010/the-story-so-far/ and http://blog.endloop.ca/blog/2010/08/12/100k-in-4-months-a-ni...
That said, I would recommend Corona - http://www.anscamobile.com/corona/ - for anyone wanting to give iPhone app development a shot. Much easier and fun to jump into than objective-c, especially if you want to make games, and still pretty damn powerful!
