2006: Smartphones were boring.
2007-2010: Smartphones become magical. The pinnacle, or close to, of the 3.5 inch phone is developed in the iPhone 4.
2010+: Phones smaller than 4.5 inches disappear; by the same magic that they used to appear.
For the people who want a 3.5 to 4 inch phone, such as myself, paradise was basically snatched away. I know they can make them, I know they run every app I care about, and they are no longer available for purchase. I want an iPhone 4. I'd settle for an iPhone 5 or similar form factor. Instead they've disappeared and best-case is maybe there is some Android phone that has the right dimensions and is probably poorly fabricated because it is targeting people on a budget.
The issue isn't even entitlement, it that the form factor situation is backsliding from where it was when I was happiest. It is infuriating.
