There's not a whole lot to say here, right? We all know the iPhone backward and forward. There's really no way not to (especially when you've got the likes of iMore.com in your stable). And after we don't know how many Samsung Galaxy S III (S3) posts, we're fairly familiar with it, too. One's metal and glass. The other is predominantly plastic. But it's a skinny bugger. Lanky, almost wiry.
Body styles notwithstanding, the major difference is in screen size. The iPhone still wins out in pixel density, but that's because it's still at a rather quaint 3.5 inches, whereas the Galaxy S3 is a whopping 4.8 inches (crammed into a slightly smaller body).
So which would you choose? Made-for-human plastic? Or the cold, hard reality of aluminum and glass?
We've got hands-on video and pics after the break.
