I'm posting this on my Thinkpad T420 with the 2520m Sandybridge i5 chip. A Snapdragon 835 benchmarks at almost exactly half the speed of this 6 year old laptop. So a chip that at best is half as fast as a low end device of more than half a decade old is now going to be loaded down even more doing "binary translation" of x86 calls into ARM. And I'm supposed to be excited?
FWIW, I dipped my toes into the Atom powered 2-in-1 market with the Acer 10 thing. It checks most of the boxes from this announcement regarding battery life, portability, etc. yet it collects dust. Why? Because it is slow. I don't care how pocketable a full Windows device is, if trying to do any real work on it is a frustrating experience of waiting that makes me want to chunk it out the nearest window, I think I'll pass.
Based on the fact that Intel couldn't even be bothered to stay in the market for this stuff leads me to believe that most other consumers agree with me.
