Anybody who has a Le Pan tried the 'ACASE for HP Touchpad' for a case option (on Amazon)? I could just get the Targus Truss Case but it is really heavy and the ACASE looks alot lighter. The Le Pan is already on the heavy side. My concern is the '4 corner' mount for the ACASE would cover up the power button on the Le Pan. Just wondering if anybody has tried one.
