The ASUS Transformer line of tablets have consistently been among the strongest contenders in the Android tablet world, so when it was announced that they would be one of the launch partners for Microsoft's Windows-on-ARM push, big things were expected. And so we have the ASUS VivoTab RT.
The VivoTab name comes from the Latin verb "to live", while the RT part is of course an indication of Windows RT, the official name for the ARM version of Windows. Windows RT-based tablets are Microsoft's first real competitors built for the modern tablet market, so this is a hugely important launch for Microsoft as well as its hardware partners. Obviously the elephant in the room here is Surface and how Microsoft entering the hardware market changes the Windows 8/RT launch, but we'll get to that part in time.
The division of Windows 8 (x86) and Windows RT (ARM) has resulted in a whole host of tablets with names ending in RT, and very similarly named examples running the x86-based Windows 8, so it's worth keeping track of. For example, the VivoTab is x86-based, with Windows 8, Clover Trail, and an 11.6" display, a completely different product than the VivoTab RT that we have in front of us today. The RT is very important in making the distinction between ARM and x86 hardware platforms.
