I never said you couldn't, but just because someone is focused on customisable in one area doesn't mean they are interested in customisable in all areas I like to customise things that are actually fun to customise, my high end PC where I'm trying to squeeze every inch of performance out, the track car which drinks gallons of fuel and eats a fresh set of tyres for breakfast, lunch and tea... not the phone I used to make meetings, ring my Mum and check my emails, not the car which I want to get me the hour to and from work as cheaply as possible
Based on the fact this is an enthusiast forum, if I were to hazard a guess at what "tech enthusiast" meant it'd be less about people who like customisable things and be more along the lines of "someone who cares more about someone elses' purchases than is typically considered sane"
Like I said I'm not going to comment on high end android vs iphone because I've never had a high end android to know. I know my low end android is a piece of shit and my iphone is wonderful but that's a different story
One of my nerd friends always talks about phones and customising phones and in the end it comes down to a discussion of "and why would I want to customise my smart phone beyond what an iphone already does" and neither of us can ever think of a good reason
Well a shining example is widgets on android. You can stick with your screen full of shortcuts. How about that piece of shite notification bar on apple? It's a half ass copy of android and is about 5% as useful.
