The company says that the multi-touch update will be the first ever offered for a full-sized tablet.
The multi-touch update will allow users to do such things as drag two fingers to scroll through the screen, spread two fingers apart to zoom in, and a special command can be assigned by the user to a two-tap gesture.
"We introduced the Latitude XT as a revolutionary product in the tablet space," said Jeff Clarke, senior vice president of Dell's product group.
"Today Dell is taking that commitment to a new level with multi-touch functionality."
The move is part of a larger effort by Dell to hype its new line of Latitude notebooks. The company expects to launch a new lineup in the coming weeks and expand the number of laptop models it offers by some 50 per cent.
The company also announced a 128 GB solid-state hard drive option. The larger drive will add at least US$649 to the system price and will only be offered on XPS and Alienware systems.
