Spike Jonze really outdid himself with that one, he took some of the principles that made Eternal Sunshine such a great movie and applied them to a new technology idea. It's not a technical story or a story from a worldwide perspective, it's about the impact it has on one human, and it's told beautifully.
Also, I'd really like to see it from the software vendors perspective, I think there were some fun conversations an that side too. :D
