Although we have not done a formal review on the Huawei S7, we found it to be one of the better 7 inch Android tablet on the market. It has a Qualcomm Snapdragon processor, both 3G and WiFi data connectivity, a good resistive screen and actual access to the Google Android Market. We have found the resistive screen to be pretty responsive... for a resistive display so definitely do not disregard this tablet.
AndroidTablet has noted that Huawei is preparing the S7 tablet to have a capacitive display. Check their site for a video demonstrating the future tablet. With a capacitive display, the Huawei S7 will be even better. Can't wait.
