If this doesn't make you think "all in one" I don't know what will...the new ViewSonic ViewDock VX1945wm and the alternate ViewDock VX2245wm bring all the device connections I would need to one space. These monitors have an iPod dock included in them, but that's not all!
Includes a sound system with integrated subwoofer, 8 in 1 card reader, USB port, headphone jack and an integrated microphone. They come in 19" and 22" models, as linked above, and have a native resolution of 1440 x 900, for the VX1945wm, while the VX2245wm has a native 1680 x 1050 resolution.
The monitors will cost you $329-$449, depending on chosen model.
