What I Want

What I want:

  • A well-designed convertible/hybrid with a productivity-ready keyboard and a touchscreen which is
  • in the region of 12" on the diagonal, and
  • running Windows 8 rather than RT. Crucially, it is
  • lighter than 1.1KG (2.4lbs), and
  • has a battery life lasting more than eight hours despite rocking
  • a decent dual-core processor - maybe comparable to an i3 - and still only
  • costs no more than £500.
Nice, but not crucial:
  • 4GB of RAM
  • Full HD screen.
I've looked high and low for something which simply ticks all of these boxes - so far in vain. But you guys are the experts.
Does such a device exist? Can it? Will it?
