I read somewhere that the spider flex 8 and white flex 8 are prototypes. White comes out in october, the spider in November. Only found one little page with that on it, so don't take that info as the absolute truth... but seems okay to me,
"for 2000 dollars that gps better know when roads are closed on thursdays, make me go faster than 0 mph, be able to tell me how much gas i have, and have a clock that isn't 3 hours ahead."
