Anything that kills x86 has to be good. I don't care if it has four cores, or 48 cores, as long as it doesn't suffer from x86, it's a step in the right direction.
But, this is obviously going to be a niche product. They really need to find a way to get rid of the x86 instruction set that plagues the computer industry. It's like God's little joke - arguably the worst instruction set created has become the most popular. Part of the move to go green should be to get rid of x86. Think of the lost performance, and extra wattage used because of it, then multiply it by the 100 of millions of computers that are being used. It might be a little per computer, but when you add it all up, it's still a huge amount.
I guess he's not entirely cruel - Unix never got popular.
