Well I got a first edition GP2X. I had been wanting a GP2X for awhile and I am very impressed withery difficult it. I expected the joystick to be flimsy, but it really has a sturdy feel to it. There is a little issue with hitting diagonals as everyone has bemoaned. I really don't see it as that bad. A lot of games don't require ultraprecision. I played Ms Pacman and did pretty well. I know a lot of people wish the GP2X had a dpad. Using a dpad with maze games like Ms Pacman is very difficult IMHO. I think if the GP2X had a dpad it would be better for durability's sake, however I have to say overall I really like the little joystick. It would be nice if on the menu you could choose 4 or 8 way.
There are a few issues like batteries. Yes it would have been much nicer to me if it had LION internally. This is certainly a high drain device that could use such a battery. I probably just need to get a better charger. The emulators are fantastic and the device is just so easy to use. there are some first edition issues such as a horizontal line on my screen. The thing is it's not noticeable on most screens. Also I like the scan line look of the screen. As I have heard others point out it looks more authentic and I agree. Anyway to me this thing is a miracle in what it can do. Being a first edition it overclocks stable to about 280 mhz. Is 280 mhz rare for mk II's? Even with the shoulda coulda-woulda's I very pleased with this system
