A leaked video reveals that the upcoming HTC Leo handset may sport a 4.3-inch multi-touch capacitive touchscreen. The news would theoretically make it the first Windows Mobile device to support multi-touch as all Windows Mobile releases to date, including the upcoming 6.5, only officially support resistive (pressure-based) touchscreens that aren't capable of the feature. A few glimpses of the interface in the video reveal that the Leo does indeed have Windows Mobile 6.5 with HTC's TouchFLO interface on top.
