The best sized phone ever.

Steve Jobs called the first release of the iPhone with its 3.5" screen, "the perfect size for human hands".

Say what you want about Steve's other claims, he was probably fairly right on that one. Humans have opposable thumbs and the average range of said thumbs when touching something cradled in the palm without external movement is about 3-4 inches.

And yet I'm typing this on a "moderate" sized Samsung A71, and to tap something on the top of the screen I need to use my other hand or shift the phone downwards in my grasp to do so.
