You've got it backwards... powering your laptop from the monitor is the killer app, meaning an end to proprietary laptop power supplies.

  Well, you've got one out of two already. :) Apple laptops can be powered by Apple external monitors. It'd be nice to have a more "universal" standard -- where I'm sitting at work right now I see one coworker with a ThinkPad plugged into an Apple monitor, and another with a MacBook Air plugged into a Samsung monitor, and that means both of them need one more outlet than I do. But that's a meeting of the brands I wouldn't hold my breath for.

    > Well, you've got one out of two already. :) Apple laptops can be powered by Apple external monitors. Well. Kinda. You still have to plug in two cables. This would allow to go down to one single cable powering the laptop and sending signals to the screen. Though, honestly, I don't trust USB to be a good protocol for transmitting a high bandwidth and very lie latency signal with it's inherently polling architecture.

      Isn't that the whole point of USB's isochronous transfer mode, where a peripheral schedules part of the total USB bandwidth budget for a regular transfer of data? USB 3.1's got similar bandwidth to Thunderbolt and HDMI 1.3, so that could work for many video applications, although not for uncompressed 4K/60Hz, although VESA Display Stream Compression could allow it to work.
