Asus and other Microsoft OEM partners have also launched their own versions of Windows RT tablets that will compete with Microsoft's Surface. It's interesting to see the different design approaches being taken, some of which are similar to Android devices currently on the market. The Asus Vivo Tab RT, for example, is based on a 1.3GHz Tegra 3 SoC with 2GB of DDR3 memory, 32GB or 64GB of on board Flash storage, and looks a lot like their Transformer Prime 10-inch slate. The internal electronics are similar to Surface, with NVIDIA's Tegra 3 claiming the lion's share of Windows RT designs at launch. Microsoft's new touch-centric OS handles smoothly on the tablet and performance looks to be impressive, especially with respect to multitasking and application switching."There's also the newly-launched Samsung Galaxy Note II (Android-based, and a so called "phablet," rather than a tablet), the Lenovo IdeaPad Yoga (an upcoming Windows RT tablet with a keyboard permanently attached), and the Archos 101 XS.
