Exactly. This is what happened with Clover Trail. Intel hyped up it's ability to perform on par with ARM while still being power efficient. While Clover Trailed powered tablets were indeed almost as power efficient as the Surface RT the desktop performance was dreadful. I've seen a lot of benchmarks comparing Bay Trail to Clover Trail, and how much faster it performs etc. but if the Desktop is still as unusable then what's the point?
As much as I like the dark titanium of my Surface RT, it gets covered in fingerprints every time I use it, which is why I'm looking forward to the natural silver colour.
