if i have a cd in my drive, a bluetooth device or a camera connected, it is displayed on the desktop. this should be extended to more periferals. if i have a webcam or a printer connected, it should be displayed on my desktop. and i should be able to print by dropping a document on the printer. take a photo by clicking the webcam.
and if we want to take this further, if i drop the webcam icon on my printer, it should take a photo, and print it. possibly with a preview window appearing. same could be used with speakers, microphone, mouse/keyboard. but too much will just be a mess.
