Hi, I have pretty specific requirements... I NEED a capacitive multi touch screen. I've messed with resistive and I hate them. I want at least a 1ghz processor, 512mb ram, USB host(if not directly on it at least with an adapter), preferably standard SD card but I realize they all seem to be microsd. Screen size isnt that important but I do prefer the 7". And most importantly imdont want to spend more than 150. I'm ok getting the Chinese knockoffs as long as there is a good hacking community behind it. Thanks
