Cupp Computing wants to combine the power of an x86 processor running Windows with the efficiency of an ARM processor running Android, and the latest iteration of that project puts a prototype ARM board inside an Asus Eee Slate EP121 tablet. The board contains a 1GHz TI OMAP 3720 processor with 512MB of RAM and shares screen, storage, and other hardware with the Intel system. In a laptop, the ARM hardware goes on a module that replaces your SATA hard drive and adds a Mini PCIe SSD, but the tablet counterpart has to squeeze in next to a modified battery and shares the built-in storage. A custom button on the side lets you instantly switch between Windows 7 and Android 2.3.4 when both are running simultaneously. Cupp is also working on being able to offload antivirus and security processes onto the ARM hardware, freeing up resources and giving Windows slightly snappier performance.
