Honestly, I got the S5 because it was what was on sale when you renewed with Verizon a few months ago and because the camera is amazing. It does fit into your pocket, with a bit of overhang, and it's a nice fit for a face (albeit a little awkward to hold if you have oddly tiny child hands... or my hands, which are a little more the norm but still come up a wee bit short).I am personally the type that doesn't want a phone, MP3 player, and tablet, so instead of compromising and getting an iPhone which would solve the first two problems, I got a Galaxy that more or less takes care of the phone/tablet thing (because the last thing I want is to have an actual tablet).
I think they're a good compromise for some people. I also love the screen on my S5 and I've accidentally put it through some shit and it's been a real trooper.
