All that for $150? The Hisense Sero 7 Pro 7-inch Android tablet has a bright HD display, a powerful quad-core Nvidia chip (great for games & videos), two cameras, Bluetooth, Wi-Fi, NFC, a memory card slot, HDMI and USB ports and Google Play access. Hisense and Nvidia's Nick Stam showed off the unit May 23 in New York. The Sero 7 Pro (top and at right next to original Amazon Kindle Fire) and the dual-core, one-camera Sero 7 LT ($99) go on sale at Walmart tomorrow. CLICK THE PIC for more info.
