You and me both. To this day I deliberately don't think about it, because it just makes me sad that what seemed to be incredible potential was shelved. I guess the Surface products are the closest to that potential, but for a long time all we had was the iPad and awful Android tablets. And I still feel like all of it doesn't live up to the ideals the Courier had.
I'm now going to go and forget this comment happened so I don't spend the day depressed about where technology went.
