Wow, what's amazing to me, is that these two guys get paid to do this. MS just announced this thing, I'm sure it has been perculating for some time, and isn't due to be finished for some time. Yet these two guys, have gall to debate its validity. I liken it to the pre-speech commentary that occurs on the political scene. Yea, they both had valid points, though I see Vaughan-Nichols arguments as more negativity and naysaying than solid criticism.
In any case, whatever actually happens with W8, 12 to 18 months down the road, whoever was closer will raise his hand and say, 'See, what did I tell you', while the other will just not mention it.
Sometimes you are the anteater, sometimes you are the ant.
