I never made any comments about Bay Trail. Indeed, Intel could use Silvermont cores to build great laptops, but they won't.
Where are the Celeron or Atom Ultrabooks? The ones with SSDs and high res displays? I don't want to pay for 6000 specints. I'd rather spend those dollars on other features.
Understandably, Intel does not want Atom or Celeron to eat the higher priced Core chips.
Perhaps there is room in the market for someone else to make a different set of tradeoffs.
