The problem with GPH is the way they lose great softwares, for example tkae the demo of Odonata.
An excellent shoot them up for their handheld but with their poor marketing and help the game was never released, now the do a new version of the GP2X with minor changes, the first one is already a good machine, it only lacks professionnal software to be much more appealing.
As you can see I already own a GP2X, I can play emulated games but I also need new and original games on the current hardware.
