>a lot of the hard problems he was discussing were completely solved by the advent of touchscreen interfaces (specifically, the ability to reconfigure the interface according to what tasks are relevant at that moment). Done right, touchscreens are a huge boon for usability (I mean, look at what the iphone did).

Eh, reconfigurability and dynamic interfaces are great for developers because it allows you to change things later and fix mistakes. Context sensitive UIs assume my brain can switch spatial contexts as well and for some interfaces, context switches are expensive on my brain. I want to rely more on muscle memory so I can focus on higher cognitive tasks, I don't want my UI to be one of those higher cognitive tasks.

Touch interfaces have their place but too many fall prey to the allure of sexy and try to slap it on every problem. On phones it ultimatelt makes sense, even there jumping between apps and updates on apps I find myself spending time figuring out interfaces far more than I should need to. This hurts usability more than helps it. I understand the goal is typi ally continuous improvement but I wonder for how many the goal is simply continous new shiny
