[color:"orange"] (there's truely no need to have 2 screens is there?). [/color]
For normal, classic gaming - no. But there are and will be games specifically using this feature in various respects.
1. the touchpad (lower screen) to manoeuvre in the game in lieu of the buttons;
2. racing games, where one screen is your rear mirror view; in adventures, where you have the map or inventory on one screen, so that you don't have to leave the game screen;...
The touchscreen allows a totally different control feature/feeling - some like it, some don't. And some games are designed to display over both screens to give a larger screen surface/overview.
