Many interesting post, with different points of view, thank you all.

As for myself I think that using a less "technical" camera can free the creative side of my brain more and give me more freedom to experiment, to escape from cliché or already seen xx times.

PS: I didn't know Sergio Larrain's letter to his nephew, thanks for this quote:
"First and foremost, you have to have a camera that fits you well, one that you like, because it’s about feeling comfortable with what you have in your hands: the equipment is key to any profession, and it should have nothing more than the strictly necessary features."
