The big story is high-end specs, ridiculously slim form factors. We've not seen an all-in-one as thin as this before, not least one packing a 4K touch display. That's probably the showstopper, but the 2-in-1 shown off is no slouch, comprising a super-thin tablet with a keyboard dock.
We've not been able to find the actual devices, but we've got a very short clip below which at least gives a glimpse at them. If this is what Skylake makes possible, sign us up.
