Why doesn it have WiMax / GPS / accelerometers / etc?
We had to draw the line somewhere. Adding any more features would have increased the price. Luckily Pandora has a fully functional USB host port, bluetooth, two SD slots with SDIO capability, and a serial UART for adding whatever additional widgets you want (such as a USB GPS system). Solder pads were designed into the PCB for “hacking” in extra internal hardware.
