I'm a fan of cheap phones or pads, but it's really amazing to see some one can make android runs on a tablet. That makes me wonder around to find the best android tablet. But as they are so many versions and prices, I'm really getting confused. There's site called androidostablet.com They divided the tablets into 3 categories, low, pro, and alu, the only difference I saw is that the low version runs on VIA 8505 300MHz CPU, and starts at $149, the pro and alu runs on RK2808 Chipset (ARM9 @ 600 MHz + DSP @ 550 MHz dual-core), and the pro has a plastic shell, but alu has aluminion shell, and pro starts at $189, alu starts at $199. I never seen any other site have such categories, but really want to know if this site give us the truth of the differences between these versions.
