Unless you've used a Zodiac, you don't know how wrong a convex pad is for a handheld. Concave is far superior.
SNK totally innovated handheld controls with their concave digital thumb stick design. GamePark was very smart to copy that brilliant design for the GP32. To lose that superior design for the sake of looks, or due to popular ignorance, would be a true misfortune.
Those of you who really don't have experience with many handhelds should maybe listen to those who have. We're trying to make the GP2X the best it can be, not just good enough.
Convex sucks. I'm going to do a complete DaveC on this matter. In fact I know DaveC agrees so hopefully he'll stop by and add his voice to the subject.
