The frontlight cover that Sony recently put out is an obvious evidence that the concept works.

The lightwedge-based frontlight has been used fort a long tine now. They were using them as aftermarket mods on the original unlit Gameboy Advance. (The old Afterburner kits, circa 2001-2002.) The Sony frontlight is just a slight resizing of old, proven technology.
