its about 1/4 to 1/2 the speed of the galaxy tab. doesnt say but im assuming its a resisitve screen which makes it a pain in the ass to use. quality of it will be low so i garentee when you are charging it and putting sound out at the same time you going to get huge electrical feedback, making it useless to listen to. However i would gladly be corrected
It's not a bad price for what it is, but you are right the Galaxy tab specs are superior in every way. *double the processor speed *double the amount of RAM *better screen resolution *includes in-build GPS *includes in-build Bluetooth *3G *4000mAh compared to 2400mAh (although not relevant if you're planing to use it exclusively in the car) *also has HDMI 1080p output with a dock link
HDMI out to a 12v receiver or maybe to a low power receiver on an inverter hidden somewhere and then to a normal amp would solve the audio quality problem.
