Microsoft garnered lots of attention when it unveiled the Surface tabletop computer, but Redmond isn't the only company interested in multitouch interfaces.

HP's giant multitouch computer was on display at The Wall Street Journal's D conference last month, just a few yards away from Microsoft's Surface.
