For too long it was the metaphorical unwanted litter of kittens tied in a sack just waiting for someone to ditch it in the river. Windows RT is dead, having enjoyed a cancer-ridden 'life' for longer than many people expected. Microsoft announced that it is no longer going to manufacture Surface devices, all but signing the death warrant for Windows RT.
Hear that sound? No? That's the sound of everyone caring about it. To be fair, the writing has been on the wall for quite some time. Windows RT was always the sickly twin sibling of Windows 8 and now Microsoft has done the decent thing. It might not quite have delivered the lethal shot to the brain yet, but the gun has been cocked. And not before time.
