I'm talking about little changes that can't be done in firmware, but not so big that it would be GP3X. Here are a few of mine.
1. Notches in the case to attach 3rd party accessories. They would be similar to how the iPod Mini and GBA/GBA SP have them. Maybe on the EXT port and above the screen.
2. Lithium ion rechargable batteries. I don't need to say why. Maybe have the same form factor as 2 AA batteries.
3. Power from USB. Is there enought mA? And have it rechargable from it.
EDIT:
4. A dimmer knob to help save battery. (Although this could be done as a mod)
