Query: Not so great

I think this system stinks. It was good in 2003, but now that it's 2006, it's time to move on with a PSP or DS. The backlight was a nice feature, but almost every handheld has that now. Mine is just sitting in my closet, picking up dust. The graphics and sound are mediocre. Eh.
