I almost bought into mirrorless, but I grabbed a canon s110 instead, cause it's smaller. I don't need an slr really, or interchangeable lenses. But people who get these because they're smaller than a dslr then drop a huge ass lens on them, that makes no sense to me. I also wouldn't mind owning one of those olympus ones with a 35mm lens stuck on it, and a 28 as backup. I've played with a ton of them at b and h, I think they're pretty nice. That sony one is supposed to be decent.
And I've gotten used to the no finder thing. A finder is clearly better, but it's whatever now.
