Everywhere outside USA, Android pretty much dominates. In Spain, Android was at 92% last time I checked and Spain isn't some third world country. Only in the States is where it seems close to 50/50 although living in SoCal, it seems more like 70/30 or 80/20 I see more iPhones. All my cousins and friends use iPhones. The de facto series.
Value for practical use vs value to resell
I was scouring OLX to check out second hand iPhone 4 and 4s. I still see them go for like $85. For resell, I see the value in owning iPhones. But I always ask myself is that 4s any better than my current phones for practical use esp this Moto E2 that I recently put a 64gb micro-sd card, 1 inch bigger screen, and compares easily to the iPhone SE in battery life? Hell no! I have an iPad 2 on 8.3 and it is slow as molasses to browse on Safari or even connect to a Wi-Fi network. So for people who brag about getting longer software support from Apple, good luck with that after three years. Downgraders are becoming more common only for Apple to force you to update to use certain apps.
The real diamonds in the rough are the budget Android phones in the sub-$200 range. These are for the folks who don't game much to buy an overpriced Qualcomm Snapdragon 8$$ series cp where you see each core at over 2 GHz during idle (check CPU throttle apps) and tends to heat up fast. They don't need "5.5 or QHD. They don't care for benchmark scores. ARM Cortex A7 is efficient enough for most users. We can also sideload apps as they are quite compatible even for older software. These budget (foodstamp) phones would destroy flagships from 3-5 years ago. The neglected and forgotten devices in some prepaid package and for being dirt cheap.
The beauty of Android comes from its versatility and practical usage value in the longer run. I hope Google gets their NEXT BILLION with Android One. That $4 smartphone in India is a start. Someday, we will all have free Internet everywhere in the next decade and we can buy cheap smartphones in a vending machine and our local convenient store that could be cheaper than our lunch. Like physical media, smartphones will be saturated and cheap enough to be disposal like soda cans, CDs, DVDs thanks to how cheap and available they will become. Our future offspring will be asking us if we used to pay $20 for a DVD? $15 for a CD? $30 for a smartphone or monthly Internet? "That's expensive!“
I look at 2013-2014 as the turning point for smartphone hardware and software. The year smartphones matured enough that flagship specs back then could still hold its own now. From 2007-2012 is when smartphones, iOS, and Android were still in puberty. Growing pains. No wonder I don't see much of Josh Vergara and Michael Fisher left PocketNow. Noah Kravitz went AWOL on us. Most of the excitement and freshness is behind us.
