One of the GP2X's more annoying features...

...is the way that the mains lead sticks out of the right-hand side of the console around halfway up. This means that you have to fit your right hand around it when using the thing. I've found that in the position that's most comfortable for me, it's quite easy to press the side of the jack plug against my little finger, making that go to sleep. Not a major problem, but something a little more attention to detail in the GP2X's initial design could probably have avoided.
