The first production run was made with pre-sale money so there was no possibility to fix them if they had problems. Fortunately GPH has fixed most of the larger issues. There's a different factory making the MK2 units (you can see a dramatic improvement in build quality), so issues like the board being misaligned in the case, the joystick having diagnol bias due to a poor orientation decision, and a poorly-selected resistor value for the screen have been found and fixed.
What bothers me is that they have no interest in ever replacing the stick, as was made clear to me by Craig (his stance is, if he can play Battle Squadron on it, it's fine. The bigger problems come in games that aren't shooters, like platformers where the long swing time from Right to Left makes stopping and turning around in Sonic or Mario difficult, playing the 3D sonic stages a real chore, or twitch movements like ducking under some bricks in World 1-2 of SMB1 while running very difficult. It also makes entering precise combos in fighting games unnecessarily tricky. I don't approve at all of one person's opinion of the stick dictating that there is no problem, when half a very large user group such as this one finds a GLARING problem, even leading to multiple stick replacement threads that gain several thousand reads and hundreds of replies of interest.
I will say though, the stick aside, the GP2X is a pretty damn solid machine. I'm kind of surprised how well it turned out on such a shoestring budget.
