Graphical calculators: when I was in high school there were these brand new high-tech graphical programmable calculators that got me wondering what great tools students of the future would have. now a dozen years later, what do high-schoolers use? The same old TI 89 that I had at the time (OK, smartphones may be taking over that niche soon, and laptops already ate up part of it). So that's one area where I was expecting progress and got nothing.
