Sorry but that took me one minute to locate. Maybe you meant that you don't find them at the corner store?
There are plenty of 11.6" touchscreen ultrabooks out there - e.g. Asus UX21A, or Acer S7-191.
But as far as I can see, none of them are available in the UK!
Does anyone know why not? Or more importantly, when one of them might be available in the UK?
Light bulbs you shouldn't buy
There are plenty of dimmable LED light bulbs, but make sure you don't buy the ones that flicker when you dial them down.
