It seems that the most telling factor is what percentage of the software is new code. Successive versions of a baseline like Android can solve a lot of problems, but how much new code is there sitting on top to achieve some new use case? For new smart devices, either the manufacturer or an outside firm is tasked with writing new code to achieve some end, and that's where the problems usually are. So it seems like as long as there are developers writing new code, our tech is going to be buggy and not quite living up to those futuristic expectations.
