I looked at my own monitor and... realized none of the 5 monitors in my home office have stands, because they are wall-mounted. Also, all of the monitors I have purchased in the last 2 years have been WQHD (2560x1440) resolution, not 1080p.
Putting a charger in the stand might be useful for a certain percentage of their customers, but it is hardly earth-shaking and revolutionary, particularly when such a device could just as easily be decoupled from the monitor completely as its own device, thus eliminating the need to have your whole monitor serviced if that one doo-dad malfunctions.
Integrating an unrelated component into the monitor is really quite useless. Better would have been to make the stand less obtrusive so a charger could easily fit below the monitor. Likewise, I don't really need a USB hub or network switch build into my monitor.
About the only usb functionality that would be useful would be a built-in KVM switch, with enough ports for keyboard, mouse/trackball, audio, web cam and a headset.
Now... if the charger also somehow wirelessly allowed your phone to interface to the screen... you'd have something, but we won't see bluetooth-like connectivity to displays for a probably five or six years down the road, at least.
