Agreed. I mean, sure it's still early for this technology, at least in term of widespread marketing, but with time I'm certain that it'll improve and become more accepted and widely used. It just takes time for new (or "iterations of existing technology") to settle in and come into use. Like home PCs, even in the 80's when the PC was first really going into production and use, it was still a novelty for most people, and few could think to afford one.
Take the IBM PC 8088, for example, in 1981. A new toy for the ages at the low cost of $3000 (over $7000 in todays money), but how many people did you know who had one sitting in their living rooms? Twenty six years later, we have three computers at home and I'm sure plenty of people here have more than that. And I'm sure that in less than a decade this technology could very well be as widespread as the LCD monitor or broadband is today (both of which also seemed out-of-reach just a few years ago).
