While on the topic is there some cheap alternatives to this that can function as a VGA/DVI/HDMI-display+USB-keyboard out today? Also would this support to use the keyboard over usb instead of Bluetooth? I have quite a few servers and various headless computers at home, every once in awhile I need to hook them up to a monitor and keyboard for some sort of debugging, today I usually carry around a spare LCD-monitor and standard keyboard however something like an empty laptop to be used as a portable terminal would be great for this.
