i just found this ds extreme for like 20 dollars, even though i already have a m3i zero and a acekard 2. so you may ask, why did this kid get such a out of date flashkart. well, i'm loving these led lights :3. and when all you listen to is rave music, this is quite good. however, i read in many places it sayd that the ds extreme has 4 gb worth of built in space. then why is it that i only get 1 1/2 gb's of space?
