Dell's Windows 8 lineup will include a range of all-in-one computers, one of which was revealed in the latest press announcement, the one that also had information on the Latitude 6430u ultrabook.
Called OptiPlex 9010 23-inch All-in-One, it has a 23-inch display, a multipoint touchscreen, not much different from the one designed into Gigabyte's model
Being business-centric, it has an articulating stand, to optimize workspace, and can be mounted on a wall as well, via a standard VESA mount.
Dell actually describes it as a good system for acting as a lobby display, thanks to its support for remote HDD management. It doesn't hurt that the camera can be rotated, so that it can be positions properly even when the AiO is tilted.
Alas, we are no closer to knowing the price of this computer than we are to finding out the selling tag of the 6430u ultrabook. We'll have to wait until next month.
