I will have to agree with this. Surprisingly the GS3 feels better in a pocket than the iphone b.c its shape and thinness. Yes, it is longer and wider, but it sits very flat.
Since the GS3 is 16x9, it is more practical to have a 4.8" screen. A phone that is 3:2 shouldn't get much bigger than 4.3-4.4" IMO.
The biggest issue for me with the new iPhone. Making it only taller feels cheap to me. 16:9 doesn't look bad at all on my GS3... but it does on the new iPhone because there is sooo much more bezel above and below the screen on the iPhone. Which makes it too long and awkward IMO. (Thankfully, they at least decreased it from roughly 0.7" down to 0.6")
