I have watched the evolution of the personal computer and the smart phone and it is absolutely impressive. I grew up during the pre-IBM PC age and I would be dating myself if I told you that my first computer program was written on punch cards.
Not certain how much better these gadgets can get since they do pretty much everything I need them to do. Faster? Okay but wifi seems to handle my needs decently well and so I don't have to use the telephone network that much.
Besides, you are limited to the size of the screen and having higher quality video is not noticeable. There is little benefit to playing hd video on a smart phone.
