Re: The 8 does prove a point
I chose an Xperia Z3 Compact due to its pocket friendly size and excellent battery life. When it died through accident I found a Nexus 5 to be light and slim enough not to be a pain in the trouser - though the battery was awful. Still, for a plastic it bounced and survived many drops into concrete - until the day it didn't.
A few years on I use my phone for more tasks than I did then, and I don't find the size of a Galaxy S8 (in a chunky case) that inconvenient. Like the Sony I appreciate the waterproofing. I was tempted by an iPhone 8 for its cameras, but it was just too big - and the S8 considerable cheaper since I bought it a few months before the release of the S9.
