Dream: Microsoft Surface With ViviTouch Cover

The TouchCover accessory for the Surface looks pretty sweet to anyone who doesn't hate it, but I wonder if Vivitouch might not help make it even better:


It's thin as hell and it wouldn't take much power or mass to give the TouchCover just a little bit of haptic feedback to make it feel just a little more like the TypeCover. As an added bonus the cover can add to the gaming experience even when flipped back. Or perhaps even while being used!

I hear haptic feedback is a summat polarising issue on phones and tablets; what's your take?
