What do you wear?
My current SE fits my biking gear pockets without fiddling, my previous Android was a bit fiddly. The one before that (my one attempt at a larger phone) fit properly in nothing I own except my winter coats. It had to live in my rucksack, so got left at home a lot, and on the desk through lunch breaks. No surprise that it wasn't many months before I Ebayed it and bought something sensible. :p
Anything bigger than the SE would sometimes fall out of my spring/autumn weight jackets if I just bent over or sat. All except SE got too big for comfort in back pocket of jeans any more. Especially as they get so thin and large as to be asking for a bent or broken phone.
I don't think that's so unusual? It's my other half who's pocket limited. :)
It reminds me of the 80s ghetto blasters fad. Size was the thing. As they got ever bigger they got far worse as there was so much resonant empty plastic and they distorted and rattled madly with volume anywhere over 2. Size and LEDs counted above all. Sound? LOL look at these LEDs man.
Most recent changes, from all manufacturers, have been deliberately consumer hostile. There's not much left to actually innovate with. Consumers don't want to keep swapping ecosystems - as that means hassle and re-buying a bunch of apps. Often they'd prefer not to even switch manufacturers if they've ended up using a cloud app for photos or something. So they just buy the next iThing from whoever even if it is too big, or is anti case because of edge to edge screens, or has a fake notch.
Talk about Emperor's new clothes.
So what can I choose that's against this trend? Oh. Nothing. Yet I need a phone, and probably an app or two for work. Best buy something or risk job loss. Even if I detest all the offerings as too big for any pocket I possess.
In your eyes it's a vote for thinner or bigger because a sale was made. No that's not how it works. It's not a simple commodity with only one feature to make, break, and validate the sale. To vote by not purchasing I'd have to cease having a mobile.
