Damn this thing is cool.
I managed to score a pre-release unit... the thing is smaller than the original GameBoy and folds like a two-way pager.
Frontlit screen, rechargable battery... and an old school control setup--personally, I think the current GBA resembles the GameGear a tad too much.
The lighting improvement alone makes it worthwhile, and literally, it is far easier on the eyes.
For $99, this thing kicks ass.
If I had an affiliate program, I would kick these out as incentives.
