ASUS announced the Transformer Book Duet that offers consumers the best of both worlds when it comes to technology and operating system preference. The ASUS Transformer Book Duet can run both Windows 8.1 and Android. While a dual-OS tablet is something they have already offered, its previous generations products featured a tablet that ran Android, and when docked with a keyboard (which included an onboard Intel Atom processor) would switch to Windows seamlessly. However, the Transformer Book Duet can switch between Windows 8.1 and Android 4.1 at the touch of a button — in either tablet mode or when docked with the keyboard. Do this all effortlessly as the inside of the machine is a Core i3 for the base model along with a gorgeous 1366×768 display. If you want to add on the options, you can select up to a Core i7 processor, 128GB SSD, and a 1080p display.
