(Also to those who say not enough people wanted a mini phone to be worth producing: I submit the case of Prego chunky pasta sauce. Not many people want a chunky pasta sauce, but you sell a whole lot more pasta sauce in total if you sell both regular and chunky pasta sauce. Malcolm Gladwell has a TED talk about this.)
There are always a bunch of us who wants a smaller phone, but the sales number indicates that we are the minority.
To some extend I also think it explains the increasingly thin phones. With the increases in screen size, they need to make the phones thinner, otherwise it would feel like a brick in your pocket.
You're right that it was good sales figures for a smartphone, but not great for an iPhone.
I presume the problem is that iPhones are a lot more expensive to produce than tomato sauce, and it's a lot more difficult to get rid of the ones that people don't buy.
What’s lagging for you? I haven’t noticed anything even remotely slow on this phone.
Not my experience, but I tend to blame the web rather than my phone when things get laggy. I estimate that my 13 is about in the middle of its life, barring unexpected rapid deceleration events.
