But it cost $500 ($700 in today's dollars) and the day-to-day utility of cellphones/blackberries had already been established for a decade. Your example doesn't seem that comparable.
All those phones did cost 200-300 IIRC. 500 was outrageously expensive. For this device it's 3500, will be much cheaper for non pro version plus production of critical components will scale up significantly. Sony can produce less than a million displays for that thing per year, it is understandable why they are expensive.
Sure, but again… it’s like 10x the price of a competing piece of equipment which is still regarded as pretty niche. In the case of an iPhone, 2x the price for 1000x the functionality was a clear “buy”. There’s a reason that among basically everyone I know (mid class millenials) scoffs at watches and iPads but is a complete iPhone addict - the value proposition is just that good. For all the talk of these ancillary/luxury devices, the fact remains that the iPhone (or Android knockoffs) is still the absolute Crown Jewel of tech that cuts across demographics in a way that their other products do not.
And to be honest, a handheld magic cube that fits in your pocket and can display anything and be interacted in any way really is as magical as it sounds. Plus it is a quite good camera as well.
I really think that smartphone design is close to the optimal sci-fi tech for humans, exactly due to it being handheld. We rely on vision and touch the most and I think it combines those well. I am almost sure that VR would even in theory get as popular as smartphones, all else being equal.
