For the Maylong M-150:
I formatted a 4GB USB Flash drive FAT32 and was able to read a .txt file stored on it with the tablet.
There is a thick cellophane film on the screen which, when removed, allows the webcam to take pictures about as good as my Acer netbook (not too great).
Downloading apps without Android Market working is like pulling teeth
I am still happy with it...so far
