The spec sheets reveal a device with a 7-inch screen, 3G and Wi-Fi connectivity, and an SD card slot. The Looking Glass will likely be announced at next week's Consumer Electronics Show (CES), which is sure to have no shortage of new tablets. Dell filed the documents for device approval by the FCC on December 17. The Looking Glass is expected to be one of the first devices to pack an Nvidia Tegra 2 processor, a powerful chip for mobile devices that can support both typical functions (like e-mail and Web browsing) as well as advanced graphics — all while preserving battery life.
