The Spark tablet has a 7 inch WVGA screen with 1 GHz AMLogic ARM Cortex-A9 processor under the hood along with Mali 400 graphics. 512MB of RAM is aboard with 4GB of native memory. The tablet does have a microSD slot and a 1.3MP front-facing camera.
You can check out the UI as the tablet is taken for a quick test drive in the video below. The UI shown is not optimized for a 7 inch display, so by May you can expect sharper and clearer images and hopefully the lagging will also be cleared up.
