I picked one up today.
I love the backlit screen, I love the flip screen design and the small size... but my main complaint is the control pad.
First of all, when flipped open the screen is heavier than the base of the system with the buttons. So because of this, it feels heavy when playing it. Also, the side with the buttons is also a bit to thin, and feels weird when holding it. The system needs some bulk in there so it feels like a controler!
As for the D-Pad... the Game Boy Color D-Pad owns this one in every way possible IMO. I understand that it needs to be like that so the screen doesn't touch it, but I don't like it.
Now I'm not saying it's bad, because the system is not bad... it still rules! It just will take some getting use to. Totally worth it for a backlit screen so I can play it on long car trips in the dark and stuff. But overall, the control pad side needs some more bulk so it's heavier and easier to grip, and the D-Pad needs to be more like the GBC D-Pad, and this thing would be perfect.
The screen itself looks beautiful... I don't think i can ever go back to playing an old Game Boy again. Well... atleast until the GB Player comes out.
And BTW, I picked mine up at Target today (did not need a presell, they had a few boxed with both colors available), and I also got a free copy of Driver 2 Advance with it. And to think I would going to go to Best Buy for the free Carying Case deal they had going...
